    class:      GridDataType0
    created:    19/11/2009
    author:     Karl Jones

    purpose:    The Grid Data record contains the actual environmental state variable data for
                each grid location. This record specifes the data sample type, the format by
                which the data are represented and the actual data values in 8-bit.

                NOTE: Data Representation Type 0 is specifcally designed to be fexible to accommodate anything
                from character data to data expressed as foating point numbers.

    size:       64 bits / 8 octets - Min size
