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.
I'm not sure what you mean.  delete it? do you not need to require it in the tests?  (I thought you were referring to a line about capybara, but it disappeared)
