compute if the x/y provide is inverted relative to storage orientation of the frame using the wcs of image.
reset processing tags fixed and local file storage enabled.

 the node properties were being set to None in batches.  Each time the call occurred
 the Node that was being updated was updated was a cached version, so the
 changes from the previous iteration were not sticking.  Now clear_tags is called
 with all the 'ops' that need to be cleared in a single statement so that all tags
 are updated in a single clear_tags.

  Storage.set_tags was modified to do a 'force=True' so that each time a tag is set
  the set is done on an non-cached version of the node.

  In storage I made the logic for which URIs to try when looking for a file a
  bit more cleaner.  Also, a locally stored version of the file is returned first, if
  the cwd contains the a file with the expected name.

some general PEP8 and testing of return types was also added.
Cleaned up some code format .. more cleaning needed.
switch to using the storage modules header constructor.

The storage module has a method for building a proper FITS header from a
 .head file and that method was reproduced, in-efficiently, here.  no longer.
Make the storage of results to vospace more robust and push to vospace even on exceptions.

The previous approach was to open a file for writing directly in VOSpace and then only write
the results if the number of bright objects detected was sufficiently high.  This made failures
frequent (VOSpace connection drops) and also made failures hard to diagnose (no results
written on exception).  The new approach is easier to diagnose issues.
stopped flipping locally stored files.

The get_image method will return a local copy of a file when possible (other change in this commit). This
allows the astrometric transform appraoch to based on a locally stored copy of th image an so flip/flopping
is handled elsewhere, nominally.

This is still fragile. There are cases when there isn't a local copy available and then we need to correctly
flip/flop the image.  implementing the fix is a TBD.
cleaned up some PEP-8 issues.

I keep cleaning various scripts so that the formatting is easier to follow.  Unit-tests would help me know I hadn't done damage.
Added branch that looks in the local disk for calibration files before going to vospace.
Corrected a syntax error that occured during PEP-8 cleanup.  That's why we do testing!
modified which processes are checked during which phase of the pipeline

this script lets me know that we need a better way of tracking pipeline success and failure.
