tests for entry and coordinate area models

test for the entry and coordinate_area models.  they are far from dry. might use contexts but I don't yet see their benefit for these. recommendations appreciated!

The files I made are "entry_spec" and "coordinate_area_spec".  The others were generated by other things.
No, you have this file is clearly changed from sometihng previously. something that was provided no doubt by suspenders. So you can simply say, `git revert spec/rails_helper.rb master`
