Mesh Collision Detection
=========================
The algorithm computes if two meshes or two groups of meshes collide.


Input
-----
Either two meshes or none (but the annotation widget should contain some meshes).


Output
------
None. The algorithm outputs the information whether meshes (groups of meshes) collide into the log window.


Description
-----------
* *When input is two meshes*.

  The algorithm prints into the log window the information whether the input meshes collide.

* *When input is empty*.

  The algorithm picks up all the meshes available from the annotation widget and lists them in a table.	A user can then assign a group to each mesh using a spinbox **Assign to group** and a button **Apply**.	When the groups are assigned, one can select the groups of interest from the **Group** spinboxes, specify the distance threshold from the **Safety distance** spinbox, and estimate the collision via the **Detect** button. The information whether the groups collide will be printed in the log window.
