Command line action factories

Description

Factories for creating instances of Sawyer::CommandLine::SwitchAction subclasses.

A factory function is a more terse and convenient way of calling the instance allocating constructors for the various subclasses of SwitchAction, and they sometimes alleviate the user from having to supply template arguments. They take the same arguments as the instance method(s) and have the same name as the class they return, except their initial letter is lower-case. These two calls are equivalent:

SwitchAction::Ptr action1 = UserAction::instance<MyFunctor>(myFunctor);
SwitchAction::Ptr action2 = userAction(myFunctor);
