Purpose

Task: https://jira.autodesk.com/browse/DYN-4836

Added the functionality to focus on the start/end nodes of the connector. These options are added to the connector context menu. I tried adding the input binding for '< 'and '>' as shortcut keys but had issues triggering them.
Will also add some tests.
