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 switched the boolean tests to this syntax. It results in sentences that aren't very grammatical sounding.  Is this a sign I should be changing my method names?
