clang build does not permit use of abs() with a float-like argument

[Jeff Kletsky]

c_evlcom_tb.cpp:14:15: error: using integer absolute value function 'abs' when argument is of floating point type [-Werror,-Wabsolute-value]
     REQUIRE((abs(j0.real() -  j0r) < eps));
              ^

$ gcc --version

Easily resolved by using std::fabs()

I had to do this also with gcc-6.1.1 (Fedora 24) to make the software compile.

This has been fixed by recent commits. Thanks for the reports.
