Changes in version 1.47.0                        

    o   The update to R4.0.2 caused warnings like:
	  Warning messages:
	  1: In .Call("bin_level", fcs@exprs, model@.tmp_tags, model@split_axis[[level]],  :
	    converting NULL pointer to R NULL.
	The c code was updated to avoid returning a null pointer.

    o   Updated citation syntax was incorporated in the CITATION file.

                       Changes in version 1.10.0                        

    o   We now require that length of sampleClasses be the same as the number of
	instances in the flowFP object.  The documentation indicated that, but
	the code didn't enforce it.

    o   Fixed a bug regarding setting sampleClasses for a flowFPPlex.  It erroneously assigned classes to only the first member of the plex.

    o   Setting sampleClasses for a fp or a pled to NULL or to a zero-length factor now results in removing sampleClasses from the fp or plex.

    o   Cleaned up documentation for flowFP-class and flowFPPlex-class.
