Started on redshiftloader.rb
Currently got as far as creating the string that need to be executed on the command line
Things still to do:
1. Handle multiple targets by properly addressing variables in config array
2. Work out how to execute commands at the command-line using Ruby
3. Find out if we need to specify the location of the input files more specifically than just using the bucket in specified in config.yml (need to better understand how alex programmed the rest of the storageloader for infobright)
