/* funzione cross-browser per referenziare gli oggetti in base al nome o all'ID
This function can be called in two ways; to reference an item in the current document:
	MWJ_findObj( NameOrId )
To reference an item in any other document in a frameset, you can choose how 
high in the frame structure to start. WARNING: - cross frame scripting will 
cause errors if your page is in a frameset from a different domain 
	MWJ_findObj( NameOrId, ReferenceToTopMostFrameToSearch )
this function is slightly bigger than the DreamWeaver function but is more 
efficient as it can also find anchors, frames, variables, functions, 
and check through any frame structure. Note that if the name refers to inputs 
in a form that share the same name, this function will return 
the collection of inputs sharing that name.*/
