Detailed Description

A wrapper class for null-terminated constant strings. Constructors make sure that the position of the '\0' terminating byte in m_str is always in sync with m_length.

This class must stay as small as possible as we often pass it and its descendants (such as Name_string) into functions using call-by-value evaluation.

Don't add new members or virual methods into this class!
