Getting data from database and getting initial screen from the last
entered measurement (in entry mode). Still some clean-up to do but
removed Unity completely. Also need to change how getting the last
three measurement as they aren't subject independant. Now, if there is
more than one measurement of the same for the same subject, they will
show. Will need to add something a little more complex to the
repository so we can use our own SQL query.
Also need to add the subject to the measurement page.
