Bit-Span is a bit-compact integer vector, meaning that it can store
integers with a fixed bit-width n, where n can range from 1 to 64
(which is in contrast to standard C/C++ arrays allowing only integers with a bit-width of 8 - char, 16 - short, 32 - int, 64 - long long, etc.).
The main class of this library is called tdc::int_vector::IntVector<T>, where T is either a plain C/C++ integer type (char,short,int,long,long long, etc.), or uint_t<n> representing numbers with bit-width n, where n can range from 1 to 64.
The interface of this class tries to ressemble the interface of std::vector<T>.
