Q1
	Modify prove.pl and golorp such that regular expression operators are supported:

		*	: zero or more
		+	: one or more
		?   : zero or one

	Then we can do shortcuts in the grammar. For example, here is a grammar
	with zero or more "very"s.

		verbphrase --> verb, [very]*,adverb, [towards], male.

	Hints:
		- you will need to define suffix operators for (?) (*) (+)
 	    - you will need to handle the grammar expansion of things like
		  [very]*. Tricky. Hint: goal_expansion can rewrite sub-terms
		- No other hints. Up to you
	
	Test:
		- Write an english.pl variant that uses all three of the above
		  regular expression operators. Call that in the usual way from
		  z.pl
