class_docstr: Parser for fortran format strings. The parse method returns a *Format
  instance.
  
  Notes
  -----
  Only ExpFormat (exponential format for floating values) and IntFormat
  (integer format) for now.
code: def _expect(self, token, tp):
      if not token.type == tp:
          raise SyntaxError()
  
imports: from __future__ import division, print_function, absolute_import
  import re
  import numpy
label_desc: Use image node_id 4 for calling the FortranFormatParser obj's underlying member method code with example usage: obj._expect(token, tp) without return types
