[tor-commits] [stem/master] Move imports to the top of files



commit e9060e62fa0317f229ec3bfdd3d821c7eb256a84
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>
Date:   Thu Dec 31 08:45:15 2015 -0800

    Move imports to the top of files
    
    Stylistic complaint E402 in the new version of pep8...
    
      line 870  - E402 module level import not at top of file | import stem.descriptor.extrainfo_descriptor
    
    Usually this is simply because I put __all__ blocks above them which is trivial
    to change. In a few cases though I reorder imports for a good reason. As such,
    adding the ability to ignore more targeted pep8 issues.
