0030092: Modeling Algorithms - Invalid result of Section operation

Browse Source 
The following improvements have been made in Boolean operations algorithm in order to fix the problem:
1. Initialization of the pave blocks which vertices have acquired the SD ones.
2. Removing from Data Structure the small edges having the same vertices on both ends (either initially or acquired).
3. Avoid adding empty SD connections when one vertex points to itself.

Test case for the issue.
