CQisLayerCoords

DataType: CQisLayerCoords

Use:
	A list of vertices on a layer

Members:
	Layer (unsigned short) : Stores the layer number.
	DataType (unsigned short) : Stores the datatype number.
	NumVert (unsigned int) : Number of vertices.
	XYCoords (CXYCoords) : List of vertex x,y co-ordinates.

Note:
	- This is used in reporting a list of potential problematic vertices on a layer for
	the add-on QFract module. The vertices might belong to different data and might be
	independent from each other. The only thing common is the layer they are on.
	- Refer to the 'SUPPORT & COMPLIANCE' section to learn about maximum layer and
	datatype numbers.
