Expose Edge Types

[cadop]

Edge type for step etc. is not exposed in C API.

EdgeSet is using intedge, which is 'lightweight', probably for performance. If performance isn't too bad, include an edgeset with cost type stored. Doesn't need to be returned with graph, but should act like a custom attribute or energy expenditure for query on an edge id.

• Expose API for Getting Edge data

  dhart/src/Cinterface/spatialstructures_C.cpp

  Line 66 in 7ce7a6a

  C_INTERFACE GetEdgeCost(

• Follow similar style for energyexpenditure to add custom edge attributes

  dhart/src/Cinterface/spatialstructures_C.cpp

  Line 395 in 4532b54

  g->AddEdges(result, AlgorithmCostTitle(COST_ALG_KEY::CROSS_SLOPE));

• Add method or overload for getting step type after the graph generator. Either add a toggle for the edge type to be recorded or overload with new method

  dhart/src/Cpp/spatialstructures/src/Edge.h

  Line 31 in 4532b54

  STEP step_type; ///< Step required to traverse this edge \see STEP for info on every step type.

• create edge struct for interfaces. mimic node example

  dhart/src/Python/dhart/spatialstructures/node.py

  Line 10 in 4532b54

  class NodeStruct(ctypes.Structure):
