Matrix2D Readme

Originally, this was a quick hack i wrote to double check my Linear algebra homework one night... since then, i've put some more time into it and tried to make it a little more open-ended.

Version 0.3:

• Cleanup of matrix creation and initialization, removed some redundant code and cleaned up the code.
• Added get_col() and get_row() and __eq__, and added some code to make it easier to work with vectors (1d matrix).

I wrote this code for fun one night, so it's not optimized or terribly well debugged. I use it to doublecheck my homework, so i'm reasonably sure it'll work for most matrices, i can't guarantee it wont fail or bomb out sometimes.
