 """ Lexer for PPAPI IDL
 
 The lexer uses the PLY library to build a tokenizer which understands both
 WebIDL and Pepper tokens.
 
 WebIDL, and WebIDL regular expressions can be found at:

   # case of a function, the function is called when a match is made. These
   # definitions come from WebIDL.
