OARIS — Track Extractors may need to know where Radar is pointing

Track Extractor functions may need to know where the (rotating) sensor which is feeding the measurements is pointing at any moment in time. E.g. to know when plots on a particular bearing would be expected to be received. There is not an interface in the OARIS specification to do this, but it is functionally coupled to the provision of plots so the plot_reporting summary use case is a natural home for it.

Create Provide Sensor Orientation use case

A new use case within the Plot Reporting summary use case is created (alongside Provide Plots) to provide the sensor orientation to functions such as track extraction. The use case is placed at compliance level 2.
Following the modeling framework for OARIS, the use case interface (for the CMS) has a single method to provide the orientation of the sensor. The sensor orientation describes its angle (azimuth and optional elevation), the coordinate orientation (using enumerate from Common Types) and its time of validity.
The coordinate orientation allows for absolute or relative interpretation of angles and defines the zero point for elevation.
