Abstract PGE400 v6.0.9; PGE411 v6.0.7; PGE412 v6.0.7; PGE421 v6.0.7; PGE422 v6.0.7

Update pre_process_*VI.c , timesat_*VI.f90, timesate_*VI_2nd.f90, gapfill_*VI.c. do_gapfill.csh

Updated code to work with collection 6 input data.

Problem Statement Generate the NACP products using the input products generated in the C6 processing of MODIS.
Description of Change Removed the dependency on internal snow mask. Now the growing season cut off is simply land surface temperature.
Products Affected MOD15A2GFS, MOD15A2PHN, MOD09A1G_EVI, MOD09A1G_NDVI, MOD09A1P_EVI, MOD09A1P_NDVI, MOD09Q1G_EVI, MOD09Q1G_NDVI, MOD09Q1P_EVI, MOD09Q1P_NDVI
Software Affected PGE400 v6.0.9; PGE411 v6.0.7; PGE412 v6.0.7; PGE421 v6.0.7; PGE422 v6.0.7
Processing String to Receive the Change Terra and Aqua Forward Processing, Terra and Aqua Reprocessing
Downstream Product Effects None
Data Granules to be Used for Science Testing Ran science test generating the product of year 2016.
Justification After upgrading to C6, the input data format/resolution changed. The internal snow mask does not work properly which introduced error in detecting growing season (shorten the growing season significantly).
Effective Date for Implementation of Change Completed.
Status Major algorithm development completed. Sadashiva Devadiga approved 09/26/2018. Gang Ye approved on 09/27/2018.
