R/populateNewDirectory.R

In Sage-Bionetworks/synapseCopyProject: Utility functions for interacting with Synapse

###Function to take a crawled synapse object and populate a new directory with the identified structure.  
###Make new folders
###Move files in a given folder
###Replace old files with Links
