Added FailureMechanismContribution which contains the contribution distribution for each failure mechanism. Implemented FailureMechanismContributionNodePresenter with basic display functionality. Implemented FailureMechanismContributionView with a table which shows the FailureMechanismContribution. Replaced placeholder on AssessmentSectionBase with a default FailureMechanismContribution. Updated logic in GuiContextMenuItemFactory, because it was not performing the expected behavior in the interface.
