Location and entry maps

used MapBox Api to generate map on location show page.  
--map displays marker for each entry near the map center.
--javascript is in the html file.  I was having trouble getting the ruby variables to work in a seperate js.erb file.  Help would be appreciated.
I put a comment here, but you can disregard it.  I was thinking about something else.  You're right.  Something I overlooked when I rebased.
