11 Apr 2004 (2.1.0):
	- Added a whole new compilation unit (n3dmath2_qdr.hpp / n3dmath2_qdr.cpp)
	about quadratic surfaces. Currently there are two quadrics implemented,
	Sphere and Plane, derived from the abstract base class Quadratic. Member
	functions for finding intersections with rays are included.
	- Removed a hack on some constructors of the matrix classes that depended
	on the assumption that function arguments are adjacent in the stack to 
	speed up the construction (by block-assigning them with memcpy).
	
27 Mar 2004 (2.0.1):
	- Changed the default scalar_t type from float to double.
	- Solved inconsistency that would not allow the lib to compile cleanly
	when changing scalar_t to double
	- Solved an issue with OpenGL integration that arose when changing
	scalar_t to double

26 Feb 2004 (2.0):
	- First release of the n3dmath 2.0 library to the public.
