                     SkipTo
Token for skipping over all undefined text until the matched expression is found.
Parameters:
False) if True, the target expression
      is also parsed (the skipped text and target expression are returned 
      as a 2-element list).
    None) used to define grammars 
      (typically quoted strings and comments) that might contain false 
      matches to the target expression
    None) define expressions that are not 
      allowed to be included in the skipped test; if found before the 
      target expression is found, the SkipTo is not a match
    Example:
   report = '''
       Outstanding Issues Report - 1 Jan 2000
          # | Severity | Description                               |  Days Open
       -----+----------+-------------------------------------------+-----------
        101 | Critical | Intermittent system crash                 |          6
         94 | Cosmetic | Spelling error on Login ('log|n')         |         14
         79 | Minor    | System slow when running too many reports |         47
       '''
   integer = Word(nums)
   SEP = Suppress('|')
   # use SkipTo to simply match everything up until the next SEP
   # - ignore quoted strings, so that a '|' character inside a quoted string does not match
   # - parse action will call token.strip() for each matched token, i.e., the description body
   string_data = SkipTo(SEP, ignore=quotedString)
