 * Creates a new cold observable that maps values observed from the source Observable to values resolved from a ReactiveCommand.
 * Essentially, this means that the command is executed whenever the source Observable resolves a new value, so long as the command is executable at the moment.
 * @param source The Observable that should be used as the trigger for the command.
 * @param obj The Reactive Object that the command exists on.
 * @param command The name of the property that holds the ReactiveCommand that should be subscribed to.
 *                Alternatively, the actual command object that should be executed can be passed in.
