Detailed Description

template<class ENUM>
class OpenMS::FlagSet< ENUM >

Stores and handles combinations of enum values, e.g. a set of flags as bits flipped in an UInt64.

Conversion from the enum is computed as `pow(2, r)`. Thus make sure that 0 <= 'r' <=63 for all enum values. Multiple enum values can be computed by bitwise 'or' (operator|=)

This class allows assignment and bit operations with itself and an object of type ENUM, i.e. not with any numeric types.
