Adds new testing functionality: an inline diff for string comparison.
Example usage:
EXPECT_THAT("Actual string", ck_tile::test::StringEqWithDiff("Expected string"));
Failure message:
Value of: "Actual string"
Expected: "Expected string"
Actual: "Actual string" (of type char [14]),
Diff: "[Expe|A]ct[ed|ual] string"
The inline-diff function uses the Wagner-Fischer algorithm to find the minimum edit distance and generate diff markers, which has O(N^2) complexity. It has optional color codes that are enabled with the matcher.
