Theme a fields using a map. Each field is given a map.

Code

  // @@BUG:  When in a view, infinite recursion if more than one value exists per field per node and "each value in it's own row" is set to false in view field settings.
  // @@BUG:  When in a view, and the multivalue option is set to "each value in it's own row" then the element is formed as a single, and SRID (projection) is nowhere to be found in $element. This is most likely a bug in geo - but i'm not sure.
