Merge branch 'master' of github.com:USGS-CIDA/nar_ui into NAWQAAN-66
Initial commit of the Coastal page with an OpenLayers map showing the
states layer, the coastal basins and the coastal sites.

Also fixed an issue where the scale control was not in the lower left
corner.
Excluded all OpenLayers related javascript files from tests. No tests
are written for these files and they are causing execution order
problems when running under phantomjs.

Retrieving the discrete concentration time series data to calculate the
value for the exceedance plot. Also did some rearranging of the code in
main.js so that code that can run before the siteInfo is done outside of
the promise resolution.
