Created a new function to test convergence. Started trying to test convergence in our program.
Multiple changes:
-Data is now split between processes instead of all processes having all data
-Changed transposeMPI() to handle data being split across processes
-Wrote a basic function for printing matrices
-Wrote a function to merge matrices that are split across processes
-Disabled OpenMP because it was causing weird problems with the data in the matrices

I compared the umax error with our own function to the output of the serial code with the same function and the errors were exactly the same and behaved as expected.
