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.

+##Compilation
+The easiest way to compile this program is by using the included cmake file. Simply run cmake,
+followed by make. The default build should use sane CFLAGS, and have the NDEBUG macro defined.  
+
+If you, for whatever reason, prefer to compile manually, just link all the
+.cpp files together in one executable. If you don't want to waste a lot of processor cycles,
+make sure to define the NDEBUG macro, as otherwise some quite CPU-heavy assertion checks are in
+place. For most compilers this can be done by passing the "-DNDEBUG" command line argument.

 ##Usage
 Using this program is quite easy: Just supply the input as command line parameters in this order:
 a1, a2, alpha, b1min, b1max, b2min, b2max, betamin, betamax
