Random Augmented Matrix Solver

Here is a simple program that generates pseudo random numbers based on python's random module. You pick the size of variables and number of equations, the program then it tries to solve the linear system. Pseudo random numbers are also agumented to the matrix for solving the linear system. Putting the matrix into rref is based on rref.py. This modules was done by Adam Sampson and works great! It abstracts fractions in a python class.
