Changed format of _params dictionaries to be more pythonic.  Also edited lines which had something to the effect of "if self.coordinate_header" as that is no longer testable in the latest astropy.  This is now a potential crash as self.coordinate_header is required in the loops.  Need to find another way to test, but with all the changes to astropy.coordinates going on, I am not going to deal with this right now.
Lots of changes while playing with SCAMP, SWarp, and SExtractor.

* Added additional info to config.
* Changed SExtractor defaults to dictionary SExtractorParams in telescope object instead of individual properties.  Propagated this in to CheckUnits and RunSExtractor.
* Renamed coordinate_WCS to center_coordinate
* Changed messaging to indicate when moon is down.
* Changed ReadImage to change working file extension to .fits from .fts if needed.
* Changes to RunSExtractor to use params dictionary (above) and also merge those with defaults.
* Added aheader option to SCAMP (the aheader will sit in the config.pathConfig path)
* Better handling of misfits when using it to write SCAMP head files back to fits header.
* Created RunSWarp method to de-distort an image based on SCAMP results
* Created GetLocalUCAC4 method to extract UCAC catalog stars for the image (work in progress)
* Removed rotation from MakeJPEG method (this will be handled by inputting SWarp de-distorted image)
* Changed how orientation is measured from WCS info in header.  Is now robust to PCn_m values being left out if they are qual to zero (which is how SWarp writes them).
* Added parameters to SWarp to carryover some header values, but not all.
* Lots of changes to MakeJPEG to have it make jpeg with catalog positions overlaid.  Appears to work now.
* Added additional temporary files to list for cleanup (less dross left over)
* Started working on MeasureZeroPoint method.
* Using SCAMP and SWarp output xml files as indicator as to whether they have been run on this image.
* Fixed annotation bug in MakeJPEG
Tweaks to logging message formatting.
Further messaging tweaks plus a messaging bug fix.
Messaging tweaks.
* Changes to RunSExtractor method to enable mode which runs association with catalog file
* Added MeasureZeroPoint method to calculate zero point
Make the a header file a property of the telescope object rather than an argument to the RunSCAMP method.
Make distortion order for SCAMP part of telescope object
Bug Fix in GetUCAC4 method
Add plotting option to MeasureZeroPoint method.
Attempted fix to make jpeg for over plot detected stars where binning would not work.  Untested!
Keep track of both filter from image header and filter used in UCAC catalog query.
Added link to PSF plot to HTML table output
Added link to Zero Point plot to HTML table output
Generated informational plots of Zero Point calculation
Fixed bug in MakeJPEG which would not mark stars correctly with binning
New, perhaps clearr, method of generating html code for links to jpegs and plots.
Bug fixes in writing of HTML results table.
Change background subtracted fits image to go to tmp directory.
