Implements curly or wavy arcs used to draw Feynman diagrams.
Amplitudes and wavelengths may be specified in the constructors, via commands or interactively from popup menus. The class make use of TCurlyLine by inheritance, ExecuteEvent methods are highly inspired from the methods used in TPolyLine and TArc. The picture below has been generated by the tutorial feynman.
