> added "Extends" keyword to DRL grammar. When a rule extends another, it will pull the entire LHS from its parent, to the current rule before execution. An example:
> rule "test rule 1"
>     enabled false
>     when
>         c: Cheese( type == "stilton" )
>     then
> 		list.add( new String ("rule 1") );        
> end 
> rule "test rule 2" extends "test rule 1"
>     enabled false
>     when
>         Cheese( price <= 6.00) from c
>     then
> 		list.add( new String ("rule 2") );       
> end 
> rule "test rule 3" extends "test rule 2"
>     when
>         Cheese( price > 1.00 ) from c
>     then
> 		list.add( new String ("rule 3") );         
> end 
> Test is in MiscTest.java
