Daily RDAHMM video updated

Because of the changes of our treatment to missing data sections, and correction of several bugs, the historical results of Daily RDAHMM are also different from previously. So we just made a new movie for the whole time since 1994 based on the new results. The new video can be accessed from the portal at http://gw11.quarry.iu.teragrid.org:8080/gridsphere/gridsphere

Modifications to DailyRDAHMM missing data treatment

We did the following modifications to the treatment of missing data in DailyRDAHMM:

1. For the input data, if the dates used for getting the input is 1994-01-01 to 2006-09-30, and we only get data for 1995-10-03 to 2006-8-22, then we will only fill those time sections between 1995-10-03 and 2006-8-22, and leave the gaps before and after as they are, in order to avoid the distortion to results;

2. For the big flat file that contains input for all stations, we use NaNs to fill all missing lines.
