Message:

Enhanced CountHydrogenBridgeBonds() a bit.

• new functions CheckHydrogenBridgeBondAngle() and CalculateAngle()
• CountHydrogenBridgeBonds() now discards when two oxygen show each both a hydrogen (two test cases in CountBondsUnitTest.cpp for this)
• this however also no effect over the criteria by Marry, Rotenberg and Turq.

• molecuilder/src/unittests/CountBondsUnitTest.cpp (modified) (7 diffs)
