The 'cmd' directory will be used to store all of the disco commands.  'create.go' and 'info.go' were created to provide a stub for moving over the current create and info functionality.  'help.go' was created to move any usage statements out of 'disco.go' and into the 'cmd' directory.  The help for 'scan' was created and added to 'help.go' to test the functionality (since I am learning the Go language as I am developing this project).
