Title: An interaction for measuring points on the plot

A measurement interaction that allows a user to click and drag on the plot to measure the distance and angle between two points. It emits the measurements as an event, so by attaching an event handler to the interaction a developer can display the information however they wish (in edit boxes or the status bar for example).

The emitted information is in world coordinates and the event handler also passes a sender which is actually the instance of InteractivePlotSurface2D that is being interacted with.

Apologies for the other modifications to the csproj caused by monodevelop when I added the Measure.cs file.
