/* Universal Signature - Creato il 13.08.2017 alle 11:27 da Leonardo Ciaccio [ leonardo.ciaccio@gmail.com ]
A COSA SERVE :
Viene utilizzata per identificare i nodi in un documento per attinenza, un po come avviene
con le classi. Caratterizza un nodo, in un insieme di nodi nel quale possono esistere nodi
simili.
DOVE UTILIZZARE QUESTA LIBRERIA
Nasce per servire plugin/estensioni nei più moderni browser, se eseguita in una qualsiasi pagina
riesce a caratterizzare ogni nodo partendo dai dati grezzi.
PERCHE'
Ogni utente utilizza il browser in modi diversi con diverse estensioni, alcune estensioni potrebbero
aggiungere/eliminare elementi nella pagina modificando di fatto il sorgente iniziale, con questa libreria
si effettua una signature su ogni elemento fissando le caratteristiche iniziali di ogni nodo per poi
essere identificate a piacimento.
IN SINTESI
Segna con un attributo 'uSignature' ogni elemento originale ( sorgente senza manipolazioni ).
FUNZIONI
uSignature.signCurrentPage( onEnd( _attrName ), onError ) // --> Segna tutti i nodi ed esegue i callback se passati
uSignature.sign( _dom ) // --> Restituisce gli elementi passati segnati
