Operator

class cee.Operator()

The Operator class is the base class for all operators. A name is required for all operators, and the name is used to identify the operator in the cee.OperatorStack.

Operators contain optional methods that correspond to the different events that may occur in the view. When an operator is set on a View, the operator can interact with its ownerView, but only that view. The cee.Viewer sets the events listeners internally, and then fires the corresponding Operator event handler method when the event is recieved.
