start	IN:	Array containing the starting coordinates of the slab
	stride	IN:	Array containing the dimensions for subsampling
	count	IN:	Array containing the size of the slab
	data	IN:	Array to hold the floating point data to be written

	Purpose	Writes a slab of data to a scientific dataset.
	Return value	Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
	Description	The start indices are relative to 1. The rank of start must be the same as the number of dimensions of the specified variable. The elements of start must be no larger than the scientific dataset's dimensions in order. The stride feature is not currently implemented. For now just pass the start array as the argument for the stride parameter, where it will be ignored.
		The rank of count must be the same as the number of dimensions of the specified variable. The elements of count must be no larger than the scientific dataset's dimensions in order. The order in which the data will be written into the specified hyperslab is with the last dimension varying fastest. The data should be of the appropriate type for the dataset. Note that neither the compiler nor HDF software can detect if the wrong type of data is used.
