/**
* \brief Passes functions to TPL functions based on type.
*
* Helper class which passes on function calls to the appropriate
* Solver function based on the type of its scalar template argument.
*
* Some Solvers have solver and matrix builder functions defined based
* on data type. One function for complex, one for double precision
* complex, another for \c float , and yet another for \c double. To
* work elegantly with the Amesos2::Solver interface we want to be
* able to perform a single function call which is appropriate for the
* scalar type of the Matrix and MultiVectors that we are working
* with. The \c FunctionMap class provides that capability.
*
* The class template is specialized for each Solver and each data
* type that it supports, and errors are thrown for other data types.
