Dan and I updated the downloading files

1. The script now moves the phenocam data and modis data to a new folder and the path is not hard coded
2. Generalized code using data file (the data file is commented out in the top of the Phenology_MODIS.R)
3. Changed from 16-day NDVI to 8-day reflectance (Dan sent out an email about this 10/10/2013).
4. We are now getting phenocam data in this script too

We need to:
1. Figure out the date issue ( and get just today for modis product)
2. Get daily modis data
