A method declaration.
methodDeclaration ::= methodSignature FunctionBody
methodSignature ::= 'external'? ('abstract' | 'static')? Type? ('get' | 'set')? methodName TypeParameterList FormalParameterList
methodName ::= SimpleIdentifier | 'operator' SimpleIdentifier
Prior to the 'extension-methods' experiment, these nodes were always children of a class declaration. When the experiment is enabled, these nodes can also be children of an extension declaration.
