Add markers for incident locations to Incident map

[jdalbey]

Part of the EI notebook is an incident map (for instructors only).
Examine the Incident script (e.g. full_script.xml) to identify the cross streets where each incident occurs. Use Google Maps to find the lat/long for each location. Add a marker to a google map and embed this in the page in the EI notebook.

In the XML file, the start of the incident should contain one or more tags like this from which the location postmile can be obtained.

			<LOCATION_INFO ID="187_N_405_ML">
				<Route>405</Route>
				<Direction>NB</Direction>
				<Postmile>8.4</Postmile>
				<Location_type>ML</Location_type>					
			</LOCATION_INFO>

As a temporary workaround I followed the directions in this tutorial:
 https://nearplace.com/blog/how-to-add-multiple-markers-on-google-maps/
to create this static google map:

We can just link to this in the EI notebook for now.

Workaround implemented. Modified einotebook/maps/index.html to embed the google map mentioned in the previous comment. Closing the ticket for now.
