//Contact Author: <thecaptcha.314159@gmail.com> <github.com/rutherblood>
//*_T.* denotes code yet to be tested
//mxMatrix: Implements Addition, Subtracion, Scalar Mult, Matrix Mult, Transpose, Determinant (if m==n), Adjoint(if m==n), Inverse(if m==n)
// Functionality To Be Added: add exception handling for mem-allocation failures on mxData
//FTBA: Add exception for n==m==0
//FTBA: Add Co-factor finding function (DONE)
//FTBA: Optimize!
