header and NiNode for now)

* created a common swig interface "common.i" to be used by all modules

* smart pointers now use the __call__() method, again this reduces the
  wrapper size

* removed __str__() from the niflib API as it does not belong there,
  instead renamed asString() to __str__() in the common.i interface

* version constants now also belong to the Niflib namespace

* SWIGFLAGS are now defined through scons environment, so we only need
  to set them once

* extra settings "-fcompact" and "-fvirtual" to SWIGFLAGS to reduce
  wrapper size

* enabled niflib as a shared library under non-win32 platforms
  (still need to find a solution for win32) under scons

* removed "pyniflib.h" and instead added CreateNiNode wrapper to ninode.i

* renamed "pyniflib.i" to "pyniflib.i_old" in case I forgot to port
  something to the new modularized system; to be removed in future

number of objects are supported so far, to reduce the size of the
wrapper. Details:

* set property eolstyle:native on .cpp and .h files for better windows + linux 
  support

* added small cpp file for quick nif read and write test (for
  debug purposes)

* fixed memory leak due to array of non-fixed sized objects:
  Header.copyright (caused segfaults under GCC)

* disabled pragma warning on NvTriStripObjects.cpp

* fixed undefined behaviour of map[...] = ... map.size() ... in
  niflib.cpp (caused segfaults under GCC)

* cleaned up SConstruct file
  - if DEBUG is false, TUNE is assumed
  - added TEST option

* workaround in pyniflib.h for ReadNifTree (need to find better solution!)

* swig wrapper interface: NiNode, NiAVObject, and NiObjectNET are
  fully supported (nothing else, for now)

* now using unittest for python test script(s)

* Renamed python.h to pyniflib.h to avoid confusion with the python.h file from python installation.
* Updated python test script.
* Enabled many things again in the swig wrapper interface, to ease debugging.
* Added "using namespace std;" in Ref.h (as in the rest of the library)

WIP: trying to make smart pointers work again with SWIG; for the moment I commented out most of the SWIG interface to reduce wrapper size and compilation time while testing

Changed some functions to use pointers instead of Ref templates.
Updated to latest XML description.

  -----   
o Exporter
  - Fix Collapse Transforms on dialog so that it actually triggers collapse
  - Change defaults for textures so Morrowind does not crash in CS
  - Fix export of animation for Morrowind
  - Introduce mechanism in Collapse Transforms so that poorly scaled models export better

o Importer
  - Fix import of animation for Morrowind

ComplexShape::Split now cuts out weights below 0.1 and normalizes the result.
Fixed a bug which could cause NiSkinInstance to try to call a function on a NiNode that was in the midst of destruction.
Removed some cout statements.

BindSkin no longer automatically clears transforms between the mesh and the root. Instead this can be done with the ApplySkinOffset function after all the shapes are in place.

Fixed strange bug.  All files now load again, and Niflib is now destroying objects properly and reporting the right number of Objects from NiObject::NumObjectsInMemory.

Generated array code now prints 20 items per 2D array in total when verbose is off.
Fixed duplicated Read call.  All FFvt3R demo files can now be read by Niflib.

Added NiGeometry::ApplyTransforms function to automatically zero out the transforms of a mesh and apply them to its vertices.
Added NiGeometryData::Transform function to apply an arbitrary transform to all vertices and normals of a mesh (used by above).
Added NiNode::PropagateTransform function to apply a NiNode's local transform to its children and then zero it out.
Fixed NiTriShapeData to properly set numTriangles when SetTriangles is called.
NiGeometry::BindSkin function now automatically propagates transforms of NiNodes between the root and the meshes and then applies those transforms to the vertices, making the NiSkinData overall transform unnecessary.
Removed "set root to scene root" option as it is no longer necessary.

Replaced GetSkinInfluencedVertices function with GetSkinDeformation function which takes in references to two vectors and fills them with the skin deformed vertices and normals
Added constructor to Matrix44 to convert from Matrix33.

Updated from XML.  Improves support for FFvt3R, but there are still problems that down show up in NifSkope.

Updated from XML, adding NiClodSkinInstance and fixing NiClodData.  Niflib can now open all Freedom Force NIF files.

Corrected Shape/particle hierarchy by adding NiGeometry and NiGeometryData.  This is the correct hierarchy and having particles come back as derived from NiTriBasedGeomData was causing problems.
Commented out printf commands in triangle stripper.

Fixed ComplexShape::Merge and ComplexShape::Split to properly take new uvSet member of TexDesc into account.
Updated Niflib for Python readme to reflect the continuing "new_niflib" name.
Reverted NiTriBasedGeom::GetSkinInfluencedVertices function to old functionality which works as long as the NIF is valid.  Some valid NIF files were not loading with the new changes.
Updated version in Doxyfile to 0.5.8

Replaced _WRITE, _READ, _STRING, AND _FIXLINKS defines with the corresponding internal function call.
Replaced STANDARD_INTERNAL_FUNCTIONS with the internal function signatures.
Made my Doxygen config file use relative paths and added it to SVN so everyone can generate the same documentation for themselves.
Removed includes WZ added to ComplexShape.  These were not missing, they are up to the user to include if they wish.

Several fixes to XML and Niflib to enable all my files from Freedom Force (except with NiClodData), Oblivion, CivIV, Morrowind, Zoo Tycoon 2, and DAoC to load in Niflib and NifSkope.
Includes the two strange Oblivion files with version 3.3.0.13 and version 10.0.1.2.

Fixed the array bug by reversing the template arguments and re-doing the declarations in the Python script.

Added support for sub version 4 headers, object storage, and link method.  Some objects like NiNodes already read correctly.

CheckNifHeader -> GetNifVersion
GetVersion -> ParseVersionString
IsVersionSupported -> IsSupportedVersion
Added new function, FormatVersionString, to format integer version numbers as a #.#.#.# string.
GetNifVersion so it no longer returns VER_UNSUPPORTED.  It now always returns the actual version value, if possible, which can be passed to IsSupportedVersion if desired.
GetNifVersion now supports version numbers lower than 4.
Added versions 4.0.0.0 and 10.1.0.106 to version constants and IsSupportedVersion function.
Updated some documentation.

Changed WriteNifTree, and WriteFileGroup functions to take NifInfo structures instead of version and user_version arguments.
Changed ReadNifList and ReadNifTree to optionally fill a passed in NifInfo structure with information from the header of the NIF file they read.
Fixed some tabs that were done with spaces instead of actual tab characters.
Updated from XML.

Removed unused vars from UpdateTangentSpace().
