Read in a matrix from a file whose name the user will specify.

There should be two integers before the matrix that denote the row and column size (No N x N matrices).

Assert that the column number and row number are both positive.

Then, read in the matrix of characters. All character will be separated by a space, this you are guaranteed.

Finally, print the desired calculations the same as Lab 2, only this time, to an output file whose name the user will specify.
