Lots of changes:
* now using datetime module instead of time
* added image_orientation() function to determine image orientation from WCS object.
* renamed many properties to have more descriptive names and use the lowercase_separated_by_underscore format for properties
* removed a few extraneous properties derived from header which were not used
* cleaned up how coordinates were read from header and turned in to satrapy.coordinates object
* changed ReadImage() method to be better organized based on file format (extension) of input file.  This is in preparation for raw conversion.
More changes to method and property names to match PEP8 convention.
Changed GetHeader() method to ReadHeader()
Working on shortening lines to get closer to PEP8 line length standard.
Finished cleaning up long lines.  Still has many lines over 80 characters, but has a lot fewer.
Removed old_MakeJPEG() method.
Changed method names to match PEP8 standards.
Additions and edits to doc strings.
Changed image_orientation() function to orientation_from_wcs() method on the Image object.
Added code to read_image() method to read DSLR raw files and convert to fits.  Still need to handle the 3 channels and still need to get header information populated.
Removed Config object and moved that functionality in to Telescope object with two properties defining the paths for temporary files and plot files.
Removed default.param as it is not used.
Various edits to fix bugs introduced in refactoring of module and property names.
Also removed singleton status from Telescope object
Edits to readme
Tweaks to reading header coordinates
Edits to orientation_from_wcs() method at SciPy sprint.  Added tests for various WCS properties.  Lots of work to do to generalize this.
Changed read_header to not add an image property to the Image object with all the image pixel data
Change handling of coordinates to match new astropy v0.4 API.
Added an example of a typical MeasureImage.py script
Bugfixes.
Bugfixes in read_image() and orientation_from_wcs() after testing with Panoptes.
Tweaks to reading of header (use try instead of of).  Changes to use of chmod for permissions in read_image (important for DSLRs).
