GetStage4Files downloads Stage IV and Stage II data files

1 2	GetStage4Files(startDate, endDate, dataTyp, dataDir, keepDownloads = FALSE, runParallel = FALSE)

`startDate`	start date + hour in the form of YYYYMMDDHH
`endDate`	end date + hour in the form of YYYYMMDDHH
`dataTyp`	name of the dataset: stage4 or stage2
`dataDir`	directory to store the data, subdirectories YYYY/MM will be created
`keepDownloads`	logical for whether to keep original download files; if FALSE, dummy empty files will be used for tracking instead to conserve space (DEFAULT=FALSE)
`runParallel`	logical for running in parallel mode (must have a parallel backend installed and registered (e.g., doMC or doParallel) (DEFAULT=FALSE)

GetStage4Files downloads Stage IV and Stage II data files from NCEP ftp site based on user configurations. The function downloads Stage IV or Stage II data from NCEP ftp site, unpacks them, and removes uncessary files (e.g., *.gif). Note for Stage II, only the multi-sensor ("ml") data files are kept while others are removed. Both Stage IV & Stage II datasets contain hourly, 6-hourly, and daily precipitation data.
