SboxSuperuser/Engine/CommandDiscovery/HandlerSignature4.cs
A generic handler signature validator for commands that take four parameters. It verifies that a MethodDescription can be bound to either a synchronous Func<T1,T2,T3,T4,CommandResult> or an asynchronous Func<T1,T2,T3,T4,Task<CommandResult>> delegate without invoking the method.
