10  """Code for normalising and formatting phone numbers 
11   
12  This doesn't (yet) try to deal with international numbers. 
13  The rule is that if the string contains 10 digits (with an optional 
14  preceding one) then it is reduced to the 10 digits (all non-digit 
15  characters removed, optional leading one removed). 
16   
17  If the string doesn't meet those criteria then it is passed through 
18  as is. 
19   
20  For formatting, 10 digit strings are formatted in standard US 
21  notation.  All others are left as is.
