/**
* Creates a breakpoint interactively, that is with user input as well as context
* information gathered from editor location. This action delegate can be
* contributed to an editor with the <code>editorActions</code> extension point.
* This action is a factory that creates another action that performs the
* actual breakpoint toggling. The created action acts on the editor's
* <code>IToggleBreakpointsTargetCExtension</code> to create the breakpoint.
* <p>
* This action should be contributed to a vertical ruler context menu via the
* <code>popupMenus</code> extension point, by referencing the ruler's context
* menu identifier in the <code>targetID</code> attribute.
