// Description : This class extends wxPanel and can substitute for the wxWidgets library class     *
//               wxSpinCtrl. It adds some useful functionality :                                   *
//                - floating point or integer numbers can be displayed,                            *
//                - incrementing by orders of magnitude not just a constant,                       *
//                - variable step size incrementing.                                               *
