The H5S_CREATE_SIMPLE function creates a simple dataspace.
            Syntax
            Result = H5S_CREATE_SIMPLE(Dimensions [, MAX_DIMENSIONS=vector] )
            Return Value
            Returns the dataspace’s identifier number. This dataspace identifier can be released with the H5S_CLOSE.
            Arguments
            Dimensions
            Set this argument to a vector containing the dimensions for the dataspace.
            Note: The Dimensions argument should be specified in IDL’s column-major order. Internally, the dimensions will be reversed to match HDF5/C’s row-major order.
            Keywords
            MAX_DIMENSIONS
            Set this keyword to a vector containing the maximum dimensions for the dataspace. The MAX_DIMENSIONS must have the same number of elements as the Dimensions argument. If MAX_DIMENSIONS is omitted then the maximum dimensions are set to Dimensions. You can use a value of -1 in MAX_DIMENSIONS to indicate an unlimited dimension.
            Note: The values specified in the MAX_DIMENSIONS keyword should be equal to or greater than the corresponding values of the Dimensions argument.
            Note: The MAX_DIMENSIONS keyword should be specified in IDL’s column-major order. Internally, the dimensions will be reversed to match HDF5/C’s row-major order.
