Title: #40 Add elementary row operations

I have added row_operators.clj and test_row_operators.clj.

The contribution is three functions for elementary row operations:

**(swap [X i j]**
swaps row i with row j

**(multiply [X i k])**
multiply row i by k

**(add [X i j k])**
add row j times k to row i
