	We thank David Dereudre for contributions.
	
OVERVIEW

    Urgent bug fix to Metropolis-Hastings for Lennard-Jones model.

    Miscellaneous additions to plotting and colour management.


NEW FUNCTIONS

        col2hex
	rgb2hex
	paletteindex
	samecolour
		Functions for converting and comparing colours.

	plot.envelope
		New method for plotting envelopes.
		By default the area between the upper and lower envelopes
		is shaded in grey.
		
IMPROVEMENTS/ENHANCEMENTS

	plot.fasp
		If the entries in the array are envelopes,
		they are plotted using plot.envelope
		(hence the envelope region is shaded grey).

        plot.fv
      	        Now displays mathematical notation for each curve,
		if legendmath=TRUE.

        print.fv
		Now prints the available range of 'r' values
		as well as the recommended range of 'r' values.
BUGS

	[1] rmh
		Simulation of Lennard-Jones model was incorrect;
		the simulations were effectively Poisson patterns.
		(Spotted by David Dereudre.)
		Fixed.

	[2] plot.fv
	        Did not correctly handle formulas that included I( )
		Fixed.
