Testcase format specifiers

[Xyene]

We need an efficient way to specify testcases in a common format for a contest, where dynamic keys are not an optimal solution. For example, the regex \w+\.(?<batch>[0-9]+)-(?<case>[0-9]+)\.in matches most, if not all, COCI data.

That's a lot of data.

That's a lot of lines of init.yml saved.

There are probably more broad ways to approach this, but for the general case a simple regex would save a lot of work, even if it loses flexibility for more complex cases (dynamic keys are there for those!)

The following should be valid, after this ticket:

test_format_in: \w+\.(?<batch>[0-9]+)-(?<case>[0-9]+)\.in
test_format_out: \w+\.(?<batch>[0-9]+)-(?<case>[0-9]+)\.out
point_values: [10, 10, 20, 60]

Someday this may be generalized to support setting a format specifier for a specific test_cases node, but that is beyond the scope of this ticket. For this ticket, if test_format_(in|out) exists, then the test_cases node should be ignored.

Hmm, you mean \w+\.(?P<batch>[0-9]+)-(?P<case>[0-9]+)\.in? I mean, we aren't going to support perl syntax for something so trivial.
