Modifying Dihedral Angles

Programs allows to modify torsion angle between atoms and molecules:

Programs opens "Modify selected dihedral angle" dialog and enters atom selection mode when user can select up to four atoms. After selecting four atoms dialog window shows current dihedral angle between selected atoms and atom selection becomes disabled. Dihedral angle between atoms can be changed by drugging the slider in dialog window or entering angle value in the text field over the slider and pressing Enter

Pressing "Reset" button resets initial geometry.

To finish "Modify selected bond" dialog one needs to press "Finish" button.
