Detailed Description

Inherits wxPanel and has a Meter; exposes shared_ptr to the Meter.

Derived classes supply implementations of its pure virtual functions, and the Meter object forwards calls to them. This indirection is done so shared_ptr or weak_ptr to Meter may be used where such pointers to wxWindow classes don't work.
