Sean Reilly baa4a437c0 Resolve issue #7902: Bugs: Division by scalar should use enable_if<> 
- This is almost identical to the fix used on #6511: Bugs: Division
  by scalar should use enable_if<> (closed: fixed)
- Scalar multiply was allowed, but divide was not.
- Updated test13 to include test of this capability
- Scaling a matrix now includes two more lines for division

  m1 * N = [3,3]((3,6,9),(12,15,18),(21,24,27))
  m1 / 2. = [3,3]((0.5,1,1.5),(2,2.5,3),(3.5,4,4.5))
