Summary	0030092: Modeling Algorithms - Invalid result of Section operation
Description	The result of Section operation is invalid (invalid point on curve). The problem has been discovered while working on the fix for the issue 0027928 in the test case bugs/modalg_7/bug26795.

SHA-1: ad9871766c929079d04d9f8792f6322e1f098e11 Detailed log of new commits: Author: emv Date: Wed Aug 29 11:51:43 2018 +0300 0030092: Modeling Algorithms - Invalid result of Section operation 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.
