36    /** Class for converting the core Ogre data types to/from Strings.
37    @remarks
38        The code for converting values to and from strings is here as a separate
39        class to avoid coupling String to other datatypes (and vice-versa) which reduces
40        compilation dependency: important given how often the core types are used.
41    @par
42        This class is mainly used for parsing settings in text files. External applications
43        can also use it to interface with classes which use the StringInterface template
44        class.
45    @par
46        The String formats of each of the major types is listed with the methods. The basic types
47        like int and Real just use the underlying C runtime library atof and atoi family methods,
48        however custom types like Vector3, ColourValue and Matrix4 are also supported by this class
49        using custom formats.
