MyersDiff works fine for non-string values

[donquixote]

The values passed to MyersDiff::calculate() don't need to be strings.
All we need is a comparison function that accepts the value types.

For the record:
I am used to Drupal doc style which I find more readable:

	* @param list<array{int, int}> $snakes Common subsequences
	* @param list<T> $a First sequence
	* @param list<T> $b Second sequence
	*
	* @return list<array{T, -1,0,1}> - pairs of token and edit (-1 for delete, 0 for keep, +1 for insert)
	* @param list<array{int, int}> $snakes
	* Common subsequences.
	* @param list<T> $a
	* First sequence.
	* @param list<T> $b
	* Second sequence.
	*
	* @return list<array{T, -1|0|1}>
	* Pairs of token and edit (-1 for delete, 0 for keep, +1 for insert)

Thanks for this. PHPDOC syntax has moved on since I wrote this package.

Thanks for the quick merging!

The @template stuff is mostly for tools like phpstan and psalm, but IDEs also support it, at least partially.

Looking again at this, I think the $a and $b parameters to calculate() should be arrays after all (not lists).

In one my applications that uses this library, the keys are not consecutive integers, which is why the function calles $a = array_values($a)
