change type in AST factory composite node method

[Stephen Siegel]

I suggest changing the type of the fields parameter in the following:

/** Alternate method to create type for unions or structs. */
	 CompositeTypeNodeIF compositeTypeNode(String name,
	           PairIF<String, TypeNodeIF>[] fields, boolean isUnion);

to ArrayList<PairIF<String,TypeNodeIF>> because Java does not allow you to instantiate an array of that type.

Will do.
