Reorganize code and variable names to make sense for other geojsons than floodplain related

Potentially try to organize rewrite so it could work for any geojson without too much effort.

Might be interesting to hear as you drive for example:

• census data
• voting district boundaries
• the wards as I can never remember how many there are or where they are.
• When you get out of City of Houston and into other municipalities due to weird boundary shapes.
• Hurricane Harvey damage?
• Property valuations?
• School districts
• Random facts pulled from some Houston Atlas
• ???

Have some documentation to make this easier now. Need to start thinking about better function and property names that would more easily enable this.
