Number element slow to decode (5 seconds to recognize number 120)

[Jason Veldicott]

It takes 4.9 seconds on my computer to decode "one hundred and twenty".  Code used is included below. 

The Number element is a great one to have, allowing natural number dictation, but this kind of delay would be noticeable during dictation.

My impression is that it may be due to a large parse tree being generated for number recognition.

Enhancement in a later version to improve speed?

words = [("one", 1000000), etc...

start = time.clock()

r=Number(name="number")         

s = state_.State(words, [], None)   # <== may need to add engine here in last arg

s.initialize_decoding()

for result in r.decode(s):

    if s.finished():                 

        root = s.build_parse_tree()                

        Text(str(root.value()), pause=0).execute()

        end = time.clock()

        print "TIME: %.2gs" % (end-start)           

        return

Oops.. it's now taking 0.8 seconds.

Not sure why the change in time taken to decode.
