Journal: Getting component and edges from point

[DHuskic]

I am trying to figure out how to get the component and edges from a point. For this journal it will have you select a corner point on a body, and from there; I plan to use the component the body is under and the respective edges from that corner to move it. I need the edges to create a csys(I have code for), I don't have code for selecting the edges. Thanks in advanced!

The following code doesn't do everything you want, but it should be a good start.
