// UrlMatcher is a class to manage the list of URLs stored in the field trial
// param. As the original data from the field trial params is delivered as a
// special format string, this class parses and formats it, and stores the list.
//
// The expected param format is a comma separated string, and each string is
// separated by the vertical bar. The left side of the vertical bar is a
// host name, and the right side is a part of path or search params.
//
// The string is something like
// "https://test.exmaple|/foo,http://another.test.example|?foo=bar,https:://yet.another.test.example"
// Then the UrlMatcher will parse it to the formatted list like
// [
//  ["https://test.example", "/foo"],
//  ["http://another.test.example", "foo=bar"],
//  ["https:://yet.another.test.example", ""]
// ]
// Based on the above list, UrlMatcher::Match() checks 1) if the given url is a
// same origin or not, 2) if it's a same origin, check the second value in the
// list item. If it's an empty string, that means origin-level url matching. If
// it has a string, check the path string and query string in the given url
// contain it or not.
