Flag and mask management
The operations use the first operand as the starting point for the result. The binary operations in this group are: bit-wise OR (equivalent to `combineWithMask()`) bit-wise AND (equivalent to `intersectWithMask()`) addition: the flags of the right operand that are defined are copied into the result subtraction: the flags of the right operand that are set are unset in the result The unary operations are: bitwise negation (equivalent to `negateMask()`) unary plus sign: no operation (bit it converts the operand to `Mask_t`) unary minus sign is not defined

Detailed Description

Classes and functions to manage bit masks and flags.

In this namespace a "hierarchy" of classes are defined:

Flag_t: a single bit; it can be initialized with the bit index, but it is stored as a bit mask. A flag has two states: set and unset.
Bits_t: a set of flags (represented as a bit mask).
BitMask: a set of flags which can have one of three states each: set, unset or undefined.
FlagSet: a set of flags (like BitMask), with the knowledge of a total number of supported flags.

The first three classes manage exactly how many bits they have storage for. FlagSet instead has also the notion of how many flags are actually supported. A number of flag-wise operations are defined. The result of an operation between two classes might be a class of a superior level in the hierarchy. In this sense, the lower objects should be intended as shortcut representations of Bits_t. More specifically:

a Bits_t can be created out of a Flag_t
a BitMask can be created out of a Bits_t (or a Flag_t)
~Flag_t is not defined
Bits_t | Bits_t and Bits_t + Bits_t are still Bits_t (and they are equivalent)
Bits_t & Bits_t and Bits_t - Bits_t are BitMask, to preserve the information of bits that are defined and unset
~Bits_t is a BitMask as well
