Initial commit of project.
data_pull.py successfully reads data from the OpenFEMA API and saves it as a .json
Updated data_pull to allow for more customization in building the request url:
-can specify version, entity, parameters independently
Added list of possible entities available from the FEMA API
Wrote a script to pull all of the different API data to local storage.
Created Tkinter interface for building queries to send to OpenFEMA API.
-Does not include support for '$filter' or different data-formats
-Requires knowledge of fields to properly use some of the options
	-there should be a way to provide a pop-up window with information of what choices are available
Updated README to be a little more descriptive
