	* EC.jj Added narrowing types conversion syntax. For now works on
 	        primitive types only. Example : "(int)1.0F".
	
	* ExpressionImage.java Several private fields were renamed and put
 		public.

	* Evaluator.java Added ability fo fix the type of the expression
 	 	result. For example, to specify : "it should be always
 	 	double.".
	
	* ExpressionImage.java 
	* CompiledExpression.java now allows to use slightly different
 		interface to compiled expressions. New interface allows to
 		avoid object creation overhead when the result of
 		evaluation is the Java primitive type. The old interface
 		is also supported. See CompiledExpression javadoc for
 		details.
