19//! A framework to define display of angles. <br>
20//! These displays are particularly useful in viewing draft prisms. <br>
21//! The angle displayed may define an intersection <br>
22//! can be between two edges or two faces of a shape <br>
23//! or a plane. The display consists of arrows and text. <br>
