DetectEdges
===========
```{function}  DetectEdges(CSX <, mesh, varargin>)
```
Full definition:
```{code-block} matlab
mesh = DetectEdges(CSX <, mesh, varargin>)
```

Returns a mesh with the edges added of certain (see below) primitives
found in the CSX structure.

optional arguments:
- mesh:       add edges to an existing (predefined) mesh

optional: 'keyword', value
- 'Debug'         enable debug mode (default is 1)
- 'AddPropertyType'  add a list of additional property types to detect
                  e.g. 'DumpBox' or {'DumpBox','ProbeBox'}
- 'SetPropertyType'  set the list of property types to detect (override default)
                  e.g. 'Metal' or {'Metal','ConductingSheet'}
- 'ExcludeProperty'  give a list of property names to exclude from
                     detection
- 'SetProperty'  give a list of property names to handly exlusively for detection

advanced options: 'keyword', value
- '2D_Metal_Edge_Res' define a one-third/two-third metal edge resolution

example:

    CSX = InitCSX();
    % define all properties and primitives to detect
    % ...
    % ...
    mesh = DetectEdges(CSX);
    mesh = SmoothMesh(mesh, lambda/20/unit);
    CSX = DefineRectGrid(CSX, unit, mesh);

Note:
- Only primitives contained in Metal, Material, Excitation, LumpedElement
  or ConductingSheet properties are processed
- Currently this function handles only Box, Polygons, LinPoly and Cylinder.
