Detailed Description

A space-time event models an event that happens at a certain 3D location, at a certain time. One use for it is in sound-based or UWB-ranging tracking or SLAM, where we have "time of arrival" measurements at a set of sensors. The TOA functor below provides a measurement function for those applications.
