public static Set<String> getNamedCaptureGroupsFromPattern(String pattern)

    Extracts the names of the named capture groups found within a regex. This function may return false positives, so you must ensure to guard against IllegalArgumentExceptions when calling Matcher.group(String). Derived from https://stackoverflow.com/questions/15588903/get-group-names-in-java-regex The returned Set preserves the order of capture groups as found in the pattern.
    
    Parameters:
    
    pattern - the pattern from which to extract the named capture groups
    
    Returns:
    
    an ordered list of named capture group candidates
