Adds a managed resource.

Adds a managed resource to the list of managed resources. Arguments passed in should describe the managed resource. If the manager is specialized to deal with e.g. ManagedSubscriber then the they should match its constructor, which in turn has to match one of the ros::NodeHandle::subscribe function.

Parameters

args	Arguments describing the resource

Returns

Returns a std::shared_ptr to the managed resource
