>  Here's my changelog:
>  -fixed Rand() so that it doesn't seed everytime and should generate better random numbers
>  - changed a few error return types to something more appropriate
>  - clean up of uninitialized variables & removal of unneccessary objects
>  - NMesh returns wrapped vectors now
>  - World returns wrapped matrices now
>  - Object.getEuler() and Object.getBoundingBox() return Wrapped data when data is present
>  - Object.getMatrix() returns wrapped data if it's worldspace, 'localspace' returns a new matrix
>  - Vector, Euler, Mat, Quat, call all now internally wrap object without destroying internal datablocks
>  - Removed memory allocation (unneeded) from all methods
>  - Vector's resize methods are only applicable to new vectors not wrapped data.
>  - Matrix(), Quat(), Euler(), Vector() now accepts ANY sequence list, including tuples, list, or a self object to copy - matrices accept multiple sequences
>  - Fixed Slerp() so that it now works correctly values are clamped between 0 and 1
>  - Euler.rotate does internal rotation now
>  - Slice assignment now works better for all types
>  - Vector * Vector and Quat * Quat are defined and return the DOT product
>  - Mat * Vec and Vec * Mat are defined now
>  - Moved #includes to .c file from headers. Also fixed prototypes in mathutils
>  - Added new helper functions for incref'ing to genutils
>  - Major cleanup of header files includes - include Mathutils.h for access to math types
>  - matrix.toQuat() and .toEuler() now fixed take appropriate matrix sizes
>  - Matrix() with no parameters now returns an identity matrix by default not a zero matrix
>  - printf() now prints with 6 digits instead of 4
>  - printf() now prints output with object descriptor
>  - Matrices now support [x][y] assignment (e.g. matrix[x][y] = 5.4)
>  - Matrix[index] = value now expectes a sequence not an integer. This will now set a ROW of the matrix through a sequence.  index cannot go above the row size of the matrix.
>  - slice operations on matrices work with sequences now (rows of the matrix) example:  mymatrix[0:2] returns a list of 2 wrapped vectors with access to the matrix data.
>  - slice assignment will no longer modify the data if the assignment operation fails
>  - fixed error in matrix * scalar multiplication
>  - euler.toMatrix(), toQuat() no longer causes "creep" from repeated use
>  - Wrapped data will generate wrapped objects when toEuler(), toQuat(), toMatrix() is used
>  - Quats can be created with angle/axis, axis/angle
>  - 4x4 matrices can be multiplied by 3D vectors (by popular demand :))
>  - vec *quat / quat * vec is now defined
>  - vec.magnitude alias for vec.length
>  - all self, internal methods return a pointer to self now so you can do print vector.internalmethod() or vector.internalmethod().nextmethod() (no more print matrix.inverse() returning 'none')
>  - these methods have been deprecated (still functioning but suggested to use the corrected functionality):
>    * CopyVec() - replaced by Vector() functionality
>    * CopyMat() - replaced by Matrix() functionality
>    * CopyQuat() - replace by Quaternion() functionality
>    * CopyEuler() - replaced by Euler() functionality
>    * RotateEuler() - replaced by Euler.rotate() funtionality
>    * MatMultVec() - replaced by matrix * vector
>    * VecMultMat() - replaced by vector * matrix
>  -  New struct containers references to python object data or internally allocated blender data for wrapping
>  * Explaination here:  math structs now function as a 'simple wrapper' or a 'py_object' - data that is created on the fly will now be a 'py_object' with its memory managed by python
>  *    otherwise if the data is returned by blender's G.main then the math object is a 'simple wrapper' and data can be accessed directly from the struct just like other python objects.
