## Detailed Description

FTLibrary class is the global accessor for the Freetype library.

This class encapsulates the Freetype Library. This is a singleton class and ensures that only one FT_Library is in existence at any one time. All constructors are private therefore clients cannot create or instantiate this class themselves and must access it's methods via the static `FTLibrary::Instance()` function.

Just because this class returns a valid `FTLibrary` object doesn't mean that the Freetype Library has been successfully initialised. Clients should check for errors. You can initialise the library AND check for errors using the following code... `err = FTLibrary::Instance().Error();`
