	Decode an unsigned variable length encoded number from the buffer back to the variable.
template<typename N >
unsigned int	osmscout::EncodeNumber (N number, char *buffer)
	Encode a number into the given buffer using some variable length encoding.
template<typename N , size_t S>
unsigned int	osmscout::EncodeNumber (N number, std::array< char, S > &buffer)
	Encode a number into the given buffer using some variable length encoding.
template<typename N >
