> This ticket adds a set of matrix math functions:
> grandSum: sum of all the values in a matrix
> sumRows: returns a vector with sums of all rows
> sumColums: returns a vector with the sums of columns
> scalarAdd: add a number to each entry in the matrix, returns s new matrix
> scalarSubtract: subtracts a number from each entry in the matrix, returns a new matrix
> scalarMultiply: multiplies a number to each entry in the matrix, returns a new matrix
> scalarDivide: divides each entry in a matrix by a number, returns a new matrix
