Need a method to solve upper and lower triangular systems
---------------------------------------------------------

                 Key: MATH-624
                 URL: https://issues.apache.org/jira/browse/MATH-624
             Project: Commons Math
          Issue Type: New Feature
    Affects Versions: 3.0
         Environment: Java
            Reporter: greg sterijevski
             Fix For: 3.0


I have run into a need to solve triangular systems. While (as Phil and Ted point out) I could
use the LU and QR decompositions, it seems cleaner to have a couple of static functions which
do this. I am including a patch to provide an implementation and the tests.
