/**
* A regular expression for breaking a URI into its component parts.
*
* {@link http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#RFC2234} says
* As the "first-match-wins" algorithm is identical to the "greedy"
* disambiguation method used by POSIX regular expressions, it is natural and
* commonplace to use a regular expression for parsing the potential five
* components of a URI reference.
*
* The following line is the regular expression for breaking-down a
* well-formed URI reference into its components.
*
* <pre>
* ^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
* 12 3 4 5 6 7 8 9
* </pre>
*
* The numbers in the second line above are only to assist readability; they
* indicate the reference points for each subexpression (i.e., each paired
* parenthesis). We refer to the value matched for subexpression <n> as $<n>.
* For example, matching the above expression to
* <pre>
* http://www.ics.uci.edu/pub/ietf/uri/#Related
* </pre>
* results in the following subexpression matches:
* <pre>
* $1 = http:
* $2 = http
* $3 = //www.ics.uci.edu
* $4 = www.ics.uci.edu
* $5 = /pub/ietf/uri/
* $6 = <undefined>
* $7 = <undefined>
* $8 = #Related
* $9 = Related
* </pre>
* where <undefined> indicates that the component is not present, as is the
* case for the query component in the above example. Therefore, we can
* determine the value of the five components as
* <pre>
* scheme = $2
* authority = $4
* path = $5
* query = $7
* fragment = $9
* </pre>
*
* The regular expression has been modified slightly to expose the
* userInfo, domain, and port separately from the authority.
* The modified version yields
* <pre>
* $1 = http scheme
* $2 = <undefined> userInfo -\
* $3 = www.ics.uci.edu domain | authority
* $4 = <undefined> port -/
* $5 = /pub/ietf/uri/ path
* $6 = <undefined> query without ?
* $7 = Related fragment without #
* </pre>
* @type {!RegExp}
* @internal
