[IDV #BYM-395795]: two things: animating times in two files and getting thredds server set up right

> Dan Tyndall here is now generating some great products of interest

Hi John,
      The trick to create the animate is to use the "Aggregate Grids by time" 
in the Data Source Type.

> Question 2: I don't think we have our thredds server set up correctly,

I think the thredds server is right.

> We have our thredds server set up by days and then products and in

when you enter the url in the catalogs chooser, use catalog.xml instead of 
.html. After that, you can select multiple files under uu2dvar, and with the 
data source type selected as "Aggregate Grids by Time". I tried it in my local 
machine and it worked.
