Modularized cache. Added table to map_helper explaining location of
moved functions.
Added binned streams. More js code modularization. Fixed right click
display values for wind.
Right click info window now asynchronously gets real data values,
fetching either from what is currently available, what is in cache, or
what it gets from a server query.

Modularized server queries, adding a second type (callback instead of
auto-populate map)
Added empty stream json files to complete the grid
