Add a way to identify the executable as a catch-test?

[janwilmans]

I propose to standardise a command-line option to identify the executable as a certain kind of test:
I will propose this to boost.test and google.test as well.

See https://github.com/janwilmans/LibIdentify

I've just pushed a commit to master that implements this. Please let me know if it looks as you intended.
(It's not in the single include yet - the next release will pick that up - but you can generate one by running the generateSingleInclude script with Python.

Just tested it, works great!

D:\project\Catch>D:\project\BoostTestUi\Debug\CatchTestSample.exe --libidentify
description: A Catch test executable
category: testframework
framework: Catch Test
version: 1.9.7

Could you also add the --wait-for-getchar option ? see https://github.com/janwilmans/LibIdentify at the bottom, it can have any name you want, so long as it does

			std::cout << "#Waiting" << std::endl;
			std::getchar();

before doing anything else in main()

[philsquared]

Done.
I've added --wait-for-keypress, which you can pass start, exit or both to (waiting for keypress on exit has been requested from time to time, so thought it makes sense to do it all together).

Both features are now on master and dev-modernise (which will be Catch2)

[janwilmans]

Great! many thanks!

Tested:

 0:10:48.32 D:\project\BoostTestUi\Debug>CatchTestSample.exe --wait-for-keypress start
...waiting for enter/ return before starting

Factorial test enter
Factorial test leave
Test2 enter

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
CatchTestSample.exe is a Catch v1.9.7 host application.
Run with -? for options

Works fine! good work!
