useful tool for uploading cyclus and cycamore

Pretty dang useful.
Hi @gidden, IFS is an internal bash variable that determines how word splitting happens. http://tldp.org/LDP/abs/html/internalvariables.html This is a fairly common pattern for the `read` command, so spaketh SO. I can add a comment that this is splitting on colons, but I don't think I should explain IFS here.
