 Routine Description:

 	Get a list of resources into the specified iterator.

 Arguments:
	
	ListIter	- A reference to the iterator class where the list is
				  accumulated.

 Return Value:
	
	A count of the number of resources.

 Routine Description:

 	Insert a resource in the dictionary.

 Arguments:
	
	pName	- Name of the resource being inserted.

 Return Value:
	
 	The resource which was created and inserted.

 Notes:

	Search for the resource, if it already exists, dont insert. This
	may really be an overkill for the code generator, since the code
	generator usually knows when to insert a resource. If necessary
	we can remove this.
