Test Suite Class

[Peter]

Clearly we need a supporting class in the tests.

Possible features:

Taking care of parsing cmd to know if we are in verbose mode. Class should have a function returning std::cout& (or ref to a /dev/null ofstream). Similarly for std::cerr.

A function (outside class) checking if two double are close. Either just check something like {fabs(rhs-lhs)<margin} or rather somthing based on the relative difference.

By design these functionality shall be independent of the library. Remember the Chicken and the Egg. If a bug in test:Suite causes a failed test is not good; but if a bug in the lib causes bad behaviour of test::Suite which in turn causes a failed test, well then it is a mess. To avoid this to happen, make this functionality independent of the yat lib.
