 *      An implementation of a graph proxy, to be subclassed and

 *  a direct graph proxy meaning that it deals with nodes.

//
// Graph Proxy Direct, this ties directly to the normal OP_Director
// node network
//

// Implements everything except for getLockedGeometry, isPaired, getSpareInput
// and all the is<NodeType>
// because there are no real default cases that make sense for them,
// as each separate OP would likely have its own version of these functions
