Class Description

 This class implements curly or wavy polylines typically 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 TPolyLine 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.

 create a new TCurlyLine with starting point (x1, y1), end point (x2,y2)
 The wavelength and amplitude are given in percent of the pad height

*-*-*-*-*-*-*-*-*-*-*Create a curly (Gluon) or wavy (Gamma) line*-*-*-*-*-*

  This member function is called when a  TCurlyLine is clicked with the locator

  If Left button clicked on one of the line end points, this point
     follows the cursor until button is released.

  if Middle button clicked, the line is moved parallel to itself
     until the button is released.
