 * @assertion Uri parse(String uri, [int start = 0, int end])
 * Creates a new Uri object by parsing a URI string.
 *
 * If start and end are provided, only the substring from start to end is parsed
 * as a URI.
 *
 * If the string is not valid as a URI or URI reference, a FormatException is
 * thrown.
 * @description Checks that components of well-formed URI match
 * appropriate regexp match groups.
 * RFC-3986 The following line is the regular expression for
 * breaking-down a well-formed URI reference into its components.
