Detailed Description

Class for converting the core Ogre data types to/from Strings.

Remarks
The code for converting values to and from strings is here as a separate class to avoid coupling String to other datatypes (and vice-versa) which reduces compilation dependency: important given how often the core types are used.
This class is mainly used for parsing settings in text files. External applications can also use it to interface with classes which use the StringInterface template class.
The String formats of each of the major types is listed with the methods. The basic types like int and Real just use the underlying C runtime library atof and atoi family methods, however custom types like Vector3, ColourValue and Matrix4 are also supported by this class using custom formats.
