Stores a vector of enum bit flags.
This is a more self-documenting and terse way to use bit flags. For example, consider this original code:
Now rewritten to use this class:

Split a vector into the individual enum values.
The enum constants are first sorted so that those with more set bits appear before those with fewer bits. Then each constant is searched in the bit vector and those bits are removed. This continues until either no bits remain or no matching constant is found. The leftovers
is set to those bits that could not be matched by this process.
