OVERVIEW
	Improvements to distance distribution code.
	Bug fixes.

NEW FUNCTIONS

        Gfox, Jfox
	        Foxall's G and J functions

	as.owin.distfun
		Extracts the domain of a distfun object.

IMPROVEMENTS/ENHANCEMENTS

	distfun
		objects of class 'distfun', when called as functions,
        	will now accept either two vectors (x,y) or a point pattern x.

	Hest
		This function can now compute the Hanisch estimator.
		It has additional arguments 'r', 'breaks' and 'correction'
		like other summary functions.
		It also has a new argument 'conditional' determining whether
		to compute the conditional or unconditional distribution.

BUGS

	[1] pixellate.psp
		Values were sometimes incorrect due to coding error.
		(Spotted by Michael Sumner)
		Fixed.

	[2] kstest
	        Crashed if the covariate contained NA's.
		Fixed.

    	[3] kstest
		Crashed if X was a multitype point pattern 
		in which some mark values were unrepresented.
		Fixed.

        [4] lurking
		Minor bug in handling of NA values.
		Fixed.

	[5] Hest
		labels of columns were incorrect.
