Map markers for multi variables different than in the legend, and won't display info when clicked

[izaslavsky]

See http://suave.sdsc.edu:3001/main/file=zaslavsk_iDigBio.csv&views=111010&view=grid, switch to map.
#multi variables (Programs, Program elementcodes, programreferencecodes) have symbols with dots - which are not in the legend. When you click on them, no info is shown in the info panel.
There is an error in console ("startRange ' of undefined())

1. Because of #multi, a tile may be copies multiple times so it triggers clicks on map. These dots will disappear if you click and unclick on them
2. I can temporarily fix it but may not be accurate for now.

With a map, we really should show only a single symbol at a location, so multi can be ignored here

Map is strictly associated with bucket views. Multiple entries are initialized when SuAVE is loaded, and in #multi we can't stop entries from intervening with each other. I tried to fix it but haven't completely resolved the problem. Now, it won't cause errors in console but still have dots when initialized. I'll try to fix it later.
