Matrix Lib Update

I have updated the Matrix Library to make it more useful. Mainly, I've removed the 2x2 limitations from calculating determinants and finding inverses. I also added several new functions:

isSize: Checks the size of a matrix by rows and columns newMatrix: Creates a new matrix of the specified size transpose: Transposes the given matrix (rows -> cols) augment: Augments A with matrix B -> AB multRow: Multiplies the given row by constant k, k != 0 multRowAdd: Multiplies the source row by constant k, k != 0 then adds that row to the dest row swapRow: Swaps row i with row j ref: Uses Gauss elimination to reduce to row-echelon format rref: Uses Gauss-Jordan elimination to reduce to reduced-row-echelon format swapCol: Swaps column i for column j delCol: Deletes the specified column delRow: Deletes the specified row minor: Returns the row minor, Mij

The most important additions were the elementary row operations, multRow, swapRow and multRowAdd - these were used to implement the row-echelon reduction methods. det(), ref() and rref() are the most *interesting* additions, although, I think the algorithms are not very efficient.
