Detailed Description

template<class Tp, Tp TInitial>
class zypp::DefaultIntegral< Tp, TInitial >

Integral type with defined initial value when default constructed.

typedef DefaultIntegral<unsigned,0> Counter;
std::map<KeyType,Counter> stats;
for ( all keys  )
  ++(stats[key]);

Todo:

maybe specialize for bool, add logical and bit operators

let TInitial default to 0 then remove base/Counter.h
