Allow using Examples after Outline

[ilyapuchka]

I noticed that there was an attempt in #14 to implement this to follow more closely standard Gherkin syntax, but it does not work well with escaping closures, so here is an alternative solution with trailing closure or parameters to pass examples after outline. Xcode indentation is a bit funky in these cases, so I'm not very confident in this approach.

Original solution for that could be possible if Gherkin syntax methods are moved out of XCTestCase and become global functions, but that will require storing a reference to currently executing test case in global variable which may lead to more complicated implementation, and will allow using these functions out of XCTestCase implementation, so is also not ideal 🤷‍♂️

Example:

        Outline({
             Given("I use the example name <name>")
             Then("The age should be <age>")
         }) {[
             [ "name",   "age", "height" ],
             [  "Alice",  "20",  "170"   ],
             [  "Bob",    "20",  "170"   ]
             ]}

         Outline({
             Given("I use the example name <name>")
             Then("The age should be <age>")
         }, Examples:
             [ "name",   "age", "height" ],
            [  "Alice",  "20",  "170"   ],
            [  "Bob",    "20",  "170"   ]
         )

@deanWombourne any thoughts on that?

Looks good, just that one question about the commented out exit code for the linter

[kerrmarin]

Is this intentional?

[ilyapuchka]

no, I forgot to remove it 🤦‍♂️

Sorry, really thought I'd approved this ages ago!
