Improved semantics of tests: non-obvious helper functions of comparison and display of matrices are replaced by the comparasion operator and the stream output operator.
Minor improvements of tests: macros for float which used for integers were replaced by macros for integers (looks like consequence of copy-paste).
Minor improvements of tests: sequence of parameters in macros was changed for more appropriate error message when test failed.
Updating to the last upstream changes (merge branch 'master' of https://github.com/saebyn/munkres-cpp).
