class TCurlyArc: public TCurlyLine

 This class implements curly or wavy arcs 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 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.

Function documentation

 Default constructor
TCurlyArc(Double_t x1, Double_t y1, Double_t rad, Double_t phimin, Double_t phimax, Double_t wl = 0.02, Double_t amp = 0.01)
 create a new TCurlyarc with center (x1, y1) and radius rad.
 The wavelength and amplitude are given in percent of the line length
 phimin and phimax are given in degrees.
void Build()
 Create a curly (Gluon) or wavy (Gamma) arc.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Compute distance from point px,py to an arc.

  Compute the closest distance of approach from point px,py to this arc.
  The distance is computed in pixels units.

void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Execute action corresponding to one event.

  This member function is called when a TCurlyArc 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.
