Matrix Multiplication!

**Objective:**

Write a program that can create two matrices and then it multiplies them!

- The user first inputs the size length and width
- Next the user populates that matrix with data
- The user then inputs the size length and width of the next matrix
- Once again they populate it
- Next the program must check to see if the dimensions match
- A n-by-m matrix can only be multiplied by a m-by-l matrix where n, m, and l correspond to the sizes of the matrices.
- If they do match correctly then create a new matrix and put the newly multiplied info inside of it.
- Multiply the individual numbers of the first matrix’s columns by the individual number of the other matrix’s row and add those together.
- The matrix size when multiplying a n-by-m by a m-by-l will result in a n-by-l matrix
