Subject: IVGCVSW-5435 Add FloatingPointComparison to remove boost::math::fpc
 uses

 * Added FloatingPointComparison.hpp and FloatingPointComparisonTest.cpp,
   which compares two floats and returns true if the values are
   within a specified or default tolerance of each other.
 * Also removed boost::math::fpc from test/TensorHelpers.hpp to validate.
