[Pyparsing] Parsing large files using SkipTo is slow.

[<Max...@dl...>]

Hello,

 I am trying to parse a simple CAD file using pyparsing, where the
 grammar is quite simple and most of the lines of the file are supposed
 to be skipped. However this is still slower than I would expect it to
 be.

 The parser is in the parse_iv.py file,  the CAD file is the
 screwdriver_2.iv and the CProfile result is th err file.

 It seems like parseString is called for each line. I don't understand
 the internal workings of pyparsing but would it be possible to use
 something like file.index( skiptostr ) to speed things up?
