How to handle --dangerWillRobinson for large amounts of files

[andreleblanc11]

There is no safeguard for preventing --dangerWillRobinson from sr3d remove to delete every single configuration in a cluster.

How to delete all of the configs on a cluster (DON'T RUN THIS):

sr3d --dangerWillRobinson remove

Suggestions:

• Have a confirmation statement before executing such a command (no config given or multiple configs given)
• Prevent dangerWillRobinson to be executed on more than one config? (This would make dangerWillRobinson defeat its own purpose)
