George Zagaris d9d6377fcb ENH: change return value to boolean 
Changed the return value of the LUFactors::Factor() and
LinearSolve() to a boolean. Updated test accordingly.

George Zagaris 73ca8f8918 ENH: avoid using magic number in LUFactors::Factor 
Add optional argument to LUFactors::Factor that prescribes
a tolernace for fuzzy comparisons. This avoids using magic
numerical values in the implementation and allows the caller
to modify the tolerance if needed. If a tolerance is not
specified, the default is set to 1.e-9.

George Zagaris 2b0ed55119 ENH: overload SetCol/SetRow to take pointers 
Overloads the SetCol and SetRow methods of the DenseMatrix class
to take raw pointers for convenience and to avoid creation of
small objects in a tight loop.

George Zagaris 0f1d8cab71 ENH: add LinearSolve(A,X) convenience routine 
This commit adds a convenience routine to solve linear systems
of the form `Ax=b` for a given square DenseMatrix instance `A`
and right handside vector, `b`. In general non-trivial case of
a matrix that is 3x3 or greater, this routine serves as a thin
wrapper around the functionality of the LUFactors class that
is provided for convenience. In addition, this commit adds
associated unit tests for the new routine.

George Zagaris 1c3735c659 ENH: add return code to LUFactors::Factor() method

zero on success and a negative integer otherwise.
