+ Filter logic supports two filter types:
+ --include-tags <regex>
+ --exclude-tags <regex>
+
+ The logic maintains a `set` of test suites.
+
+ If the regex provided with the `--include-tags` flag matches a tag of a
+ suite, that suite will added to the set.
+
+ If the regex provided with the `--exclude-tags` flag matches a tag of a
+ suite, that suite will removed to the set.
+
+ Suites can be added and removed multiple times.
+
+ First Flag Special Case Logic:
+ If include is the first flag, start with an empty set of suites.
+ If exclude is the first flag, start with the set of all collected suites.
+
+
+ Let's trace out the set as we go through the flags to clarify::
+
+ # Say our collection of suites looks like this: set(suite_ARM64,
+ # suite_X86, suite_Other).
+ #
+ # Additionally, we've passed the flags in the following order:
+ # --include-tags "ARM64" --exclude-tags ".*" --include-tags "X86"
+
+ # Process --include-tags "ARM64"
+ set(suite_ARM64) # Suite begins empty, but adds the ARM64 suite
+ # Process --exclude-tags ".*"
+ set() # Removed all suites which have tags
+ # Process --include-tags "X86"
