* bugfix in SolveTriangular found by Timothy Hunter (did not compiled for very small fixed size matrices)

Browse Source 
* bugfix in Dot unroller
* added special random generator for the unit tests and reduced the tolerance threshold by an order of magnitude
  this fixes issues with sum.cpp but other tests still failed sometimes, this have to be carefully checked...
