Add Support for Switch Cases

[dansiegel]

Description

Currently we have support for logical cases like if else if else.. but it would be helpful to have builder extensions on the code writer to better support easily building switch cases.

// expected output
switch(someValue)
{
    case "Foo":
        DoFoo();
        break;
    case "Bar":
        DoBar();
        break;
    default:
        DoBaz();
        break;
}
