This is the first test for a generic test suite for geometric functions.
The tests run are for fillet corners of SHAPE_POLY_SETS.
Previously, SHAPE_POLY_SET::Fillet was tested against CPolyLine::Fillet
to ensure compatibility. However, thse two functions now have different
interfaces and are not directly comparable. Also, this depended on
CPolyLine::Fillet being correct, which was not tested.
Instead, test SHAPE_POLY_SET::Fillet using tests against geometric
constraints, independent of any other fillet implementation.
This test is not really concerned with generic geometric code testing,
but rather the correctness of a refactoring effort.
Rename it make this clearer, and also to make way for generic geometry tests.
Adds BOOST tests to the qa folder included in the geometry subdirectory.
The tests check whether the refactored code is consistent with the
legacy code. They also check some of the new code, as the family of
ITERATOR classes.
