Searching with Picker Cells

[dooleydevin]

Currently, once something is selected in a picker cell, we do not search using that term. This was due to a rush at the end of the 2017 spring semester. This will be difficult to test; until we have a server to work with we may need to create more dummy data.

Attempt: 1. make the cell height zero, when needed
2. declare a dictionary in the back-end as a global for the front end
