[ANN] gmpxx_mkII.h: Yet another GMP C++ Wrapper for High-Precision Calculations

[maho nakata]

Dear Hans Åberg

I don't use templates extensively, and I implemented mpf_class as a typical class.
For performance comparison, please have a look,

Best regards,

In view of C++11 move operators and C++17 copy elision, I wonder if there is any performance gain by the use of templates. They seem to make user programming difficult. (I have my own C++ wrapper.) —Performance comparisons would be interesting.
