Add angle sets (disjoint ranges) - initial support

By adding a new angleset class, things get much easier to read. Also, the part of the previous commit that dealt with combining the individual ranges was kind of stupid.
Things missing:
o) functions to remove angle ranges from a set
o) deferred add functions, that allow adding multiple ranges without calling the O(n²) function angleset::combine() in between.
