From Andrei & Ivana This patch with fixes to TGeoPcon;  it corrects two bugs in the initialization  of constructors:  - in TGeoPcon::TGeoPcon()    missing :TGeoBBox(0, 0, 0) caused that    the TGeoPgon created via TGeoPgon(Double_t *param)    was never added to the list of shapes  - in TGeoPcon::TGeoPcon(Double_t *param)    not initializing fRmin, etc.    caused break as the arrays were not created    in SetDimensions() function

This patch with fixes to TGeoPcon;
 it corrects two bugs in the initialization
 of constructors:
 - in TGeoPcon::TGeoPcon()
   missing :TGeoBBox(0, 0, 0) caused that
   the TGeoPgon created via TGeoPgon(Double_t *param)
   was never added to the list of shapes
 - in TGeoPcon::TGeoPcon(Double_t *param)
   not initializing fRmin, etc.
   caused break as the arrays were not created
   in SetDimensions() function
