libremetaverse/libsecondlife/libsecondlife.Tests/TypeTests.cs
John Hurliman 65f224ad2b * Updated the unit tests to compile and run 
* Added several new methods for converting between euler angles (stored in LLVector3), quaternions and matrices. Most of the new methods are commented out as the math is currently buggy and needs more unit testing to fix
