searchableExtrudedCircle / extrudedCircle uses wrong search sphere
Summary
The analytical shape 'extrudedCircle' does not interpret the search distance correctly. It is taken as the distance to the centre line instead of the distance to the cylinder itself.
Steps to reproduce
Use in e.g. a snappyHexMeshDict. Set the snapping distance (snapTol) to e.g. 1. Make sure that the centre line is more than 1 edge distance away from the geometry. Now it will not be attracted to the extrusion, even when the extrusion itself might intersect the geometry.
Example case
What is the current bug behaviour?
What is the expected correct behavior?
Re-work the search distance into distance-to-extrusion
