> These changes allow primitive types to be requested as different types than what is stored in the file format using a flag to turn off strict type checking (default is on). Types are cast to the requested type where possible and will suffer precision loss for casting where necessary (e.g. requesting a double as an int).
> No performance penalty is imposed for using the type defined in the file type. A flag exists to
> A 6x6 test case is provided to test conversion between the primitive types.
