How to remove a node?

[RenaKunisaki]

I don't see any method for it. this->flow.getNodes().clear() doesn't appear to be working.

To destroy a single node the standard procedure would be to mark it as destroyed (eg. BaseNode::destroy()) and then it will be removed upon the next draw (eg. ImNodeFlow::update()).

With that said getNodes().clear() should also work as it returns a reference (though the comment says const reference, but the function isn't marked as const nor returns a const) to the map containing shared_ptrs to the nodes so clearing them should delete them (and thus the nodes will be gone).
