Based on {@link laas.friends.cosmopen.graphAnalysis} and {@link laas.friends.cosmopen.interpreter}, this package implements commands that can be used in the interpreter. All commands are subclass of the class {@link laas.friends.cosmopen.interpreter.Command Command} that is found in the {@link laas.friends.cosmopen.interpreter interpreter} package. The class {@link laas.friends.cosmopen.commands.GraphVariable GraphVariable} is responsible for the remaining bookkeeping of variables and value.
