Subject: [PATCH] First cut at a C++ interface to Qhull.
Includes QTest files for each class and user-eg3.c for demonstrating the interface.
See src/Changes.txt for change notes and to do.
See FIXUP for problems
See WARN64 for 64-bit problems

+<h2><a href="#TOC">»</a><a name="cpp">Calling Qhull from
+C++ programs</a></h2>
+
+<p><b>Warning:</b> The C++ interface to Qhull is new and
+incomplete. You will need to extend the interface for all
+but the simplest applications.
+You will need to understand the data structures and read the code.
+Most users will find it easier to call Qhull as an external
+command.
+
+<p>
+Qhull's C++ interface provides wrapper classes for Qhull and Rbox. It provides access to Qhull's data structures.
+Most of the classes derive from the corresponding qhull data structure.
+For example, <a href="#facet-cpp">QhullFacet</a> is an instance of Qhull's <a href="../src/qhulllib.h#facetT">facetT</a>.
+</p>
+
+The main methods are
+<ul><li>
+ <code>RboxPoints.appendRandomPoints</code> -- append random points according to rbox options.
+ </li><li>
+ <code>Qhull.runQhull</code> -- construct the convex hull of the input points
+ </li><li>
+ <code>Qhull.outputQhull</code> -- write output according to Qhull options
+</li></ul>
+
+The sample program,
+<a href=../cpp/user_eg3.cpp>user_eg3.cpp</a>, duplicates Qhull's facet dump (option 'f').
+
+Example (c.f., <code>user_eg3 eg-100</code>)
+<pre>
+ RboxPoints rbox;
+ rbox.appendRandomPoints("100");
+ Qhull qhull;
+ qhull.runQhull("", rbox);
+ QhullFacetList facets(qhull);
+ cout<< facets;
+</pre>
+
+<p>
+The C++ iterface for RboxPoints redefines the fprintf() calls
+in rboxlib.c. Instead of writing its output to stdout, RboxPoints appends
+the output to a std::vector.
+The same technique may be used for calling Qhull from C++.
+</p>
+<ul><li>
+Run Qhull with option '<a href="qh-optt.htm#Ta">Ta</a>' to annotate the
+output with qh_fprintf() identifiers.
+</li><li>
+Redefine qh_fprintf() for these identifiers.
+</li><li>
+See RboxPoints.cpp for an example.
+</li></ul>
+<p>
+A more flexible approach extends Qhull's classes. For example,
+to access the vertices of a <a href="#facet-cpp">QhullFacet</a>,
+define a constructor of <a href="#vertexset-cpp">QhullVertexSet</a>
+that takes a QhullFacet as a parameter. Please send these extensions
+to bradb@shore.net for incorporation into Qhull.
+</p>
+<p>
+With care, you may create multiple Qhull instances, but only one instance may be active at time.
+The Qhull library refers to Qhull's data structures through a global pointer <code>qh_qh</code> that
+points to <a href="#qh-cpp">QhullQh</a>. The class <a href="#usingqhull-cpp">UsingQhullLib</a> checks
+that qh_qh is correct. The QhullQh functions <code>startQhullAccess()</code> and <code>stopQhullAccess()</code> acquire and release the
+<code>qh_qh</code> pointer.
+</p>
+
+<h3><a href="#TOC">»</a><a name="coordinate-cpp">CoordinateIterator</a></h3>
+<p>
+A CoordinateIterator or ConstCoordinateIterator [RboxPoints.cpp] is a <code>std::vector<realT>::iterator</code> for Rbox and Qhull coordinates.
+It is the result type of <a href="#rbox-cpp">RboxPoints</a>.coordinates().
+</p>
+
+<p>Qhull does not use CoordinateIterator for its data structures. A point in Qhull is an array of reals instead of a std::vector.
+See <a href="#point-cpp">QhullPoint</a>.
+</p>
+
+<h3><a href="#TOC">»</a><a name="qhull-cpp">Qhull</a></h3>
+<p>
+Qhull is the top-level class for running Qhull.
+It initializes Qhull, runs the computation, and records errors.
+It provides access to the global data structure <a href="#qh-cpp">QhullQh</a>,
+Qhull's <a href="#facet-cpp">facets</a>, and <a href="#vertex-cpp">vertices</a>.
+</p>
+
+<h3><a href="#TOC">»</a><a name="error-cpp">QhullError</a></h3>
+<p>
+QhullError is derived from <code>std::exception</code>. It reports errors from Qhull and captures the output to stderr.
+</p>
+
+<p>
+If error handling is not set up, Qhull exits with a code from 1 to 5
+[qh_ERR* in qhulllib.h via qh_exit() in usermem.c]. The C++ interface does not report the
+captured output in QhullError. Call Qhull::setErrorStream to send output to cerr instead.

+The identity pipe for Qhull reveals some precision questions for
+halfspace intersections. The identity pipe creates the convex hull of
+a set of points and intersects the facets' hyperplanes. It should return the input
+points, but narrow distributions may drop points while offset distributions may add
+points. It may be better to normalize the input set about the origin.
+For example, compare the first results with the later two results: [T. Abraham]
+<blockquote>

+
+ <rf:item id="collection-api" title="API for Qhull collections" date="Feb 2009" author="bbarber">
+ Qhull's collection APIs are modeled on Qt's collection API (QList, QVector, QHash). They support STL and Qt programming.
+
+ Some of Qhull's collection classes derive from STL classes. If so,
+ please avoid additional STL functions and operators added by inheritance.
+ These collection classes may be rewritten to derive from Qt classes instead.
+
+See <rf:iref item="cpp-collection-api"/>.
+
+ Qhull's collection API (where applicable). For documentation, see Qt's QList, QMap, QListIterator, QMapIterator, QMutableListIterator, and QMutableMapIterator
+ <ul><li>
+ STL types [list, qlinkedlist, qlist, qvector, vector] -- const_iterator, iterator
+ </li><li>
+ STL types describing iterators [list, qlinkedlist, qlist, qvector, vector] -- const_pointer, const_reference, difference_type,
+ pointer, reference, size_type, value_type.
+ Pointer and reference types not defined if unavailable (not needed for <algorithm>)
+ </li><li>
+ const_iterator, iterator types -- difference_type, iterator_category, pointer, reference, value_type
+ </li><li>
+ Qt types [qlinkedlist, qlist, qvector] -- ConstIterator, Iterator, QhullclassIterator, MutableQhullclassIterator.
+ Qt's foreach requires const_iterator.
+ </li><li>
+ Types for sets/maps [hash_map, QHash] -- key_compare, key_type, mapped_type
+ </li><li>
+ Constructor -- default constructor, copy constructor, assignment operator, destructor
+ </li><li>
+ Conversion -- to/from/as corresponding C, STL, and Qt constructs. Include toQList and toStdVector (may be filtered, e.g., QhullFacetSet).
+ Do not define fromStdList and fromQList if container is not reference counted (i.e., acts like a value)
+ </li><li>
+ Get/set -- configuration options for class
+ </li><li>
+ STL-style iterator - begin, constBegin, constEnd, end, key, value, =, *, [], ->, ++, --, +, -, ==, !=, <,

+ An iterator is an abstraction of a pointer. It is not aware of its container.

+ Java-style iterator [qiterator.h] - countRemaining, findNext, findPrevious, hasNext, hasPrevious, next, peekNext, peekPrevious, previous, toBack, toFront, = Coordinates
+ </li><li>
+ Mutable Java-style iterator adds - insert, remove, setValue, value
+ </li><li>
+ Element access -- back, first, front, last
+ </li><li>
+ Element access w/ index -- [], at (const& only), constData, data, mid, value
+ </li><li>
+ Read-only - (int)count, empty, isEmpty, (size_t)size. Count() and size() may be filtered. If so, they may be zero when !empty().
+ </li><li>
+ Read-only for sets/maps - capacity, key, keys, reserve, resize, values
+ </li><li>
+ Operator - ==, !=, +, +=, <<
+ </li><li>
+ Read-write -- append, clear, erase, insert, move, prepend, pop_back, pop_front, push_back, push_front, removeAll, removeAt, removeFirst, removeLast, replace,
+ swap, takeAt, takeFirst, takeLast
+ </li><li>
+ Read-write for sets/maps -- insertMulti, squeeze, take, unite

+ Search -- contains(const T &), count(const T &), indexOf, lastIndexOf
+ </li><li>
+ Search for sets/maps -- constFind, lowerBound, upperBound
+ </li><li>
+ Stream I/O -- stream <<
+ </li></ul>

+ </li><li>
+ STL constructors -- MyType(), MyType(count), MyType(count, value), MyType(first, last),

+ </li><li>
+ STL modifiers -- assign, clear, erase, insert, pop_back, push_back, reserve, resize, swap
+ </li><li>
+ </li></ul>
+

+ </li><li>
+ Additional Qt operators -- +, <<, +=,

+ Unsupported types by Qt -- allocator_type, const_reverse_iterator, reverse_iterator

+ </li><li>
+ unsupported modifiers by Qt -- assign, muli-value inserts, STL's swaps
+ </li><li>

+ STL map and Qt QMap. These use nearly the same API as list and vector classes. They add the following.
+ <ul><li>
+ STL types -- key_compare, key_type, mapped_type
+ </li><li>
+ STL search -- equal_range, find, lower_bound, upper_bound
+ </li><li>
+ Qt removes -- equal_range, key_compare
