+ * @fileoverview Class for parsing and formatting URIs.
+ *
+ * Use goog.Uri(string) to parse a URI string. Use goog.Uri.create(...) to
+ * create a new instance of the goog.Uri object from Uri parts.
+ *
+ * e.g: <code>var myUri = new goog.Uri(window.location);</code>
+ *
+ * Implements RFC 3986 for parsing/formatting URIs.
+ * http://www.ietf.org/rfc/rfc3986.txt
+ *
+ * Some changes have been made to the interface (more like .NETs), though the
+ * internal representation is now of un-encoded parts, this will change the
+ * behavior slightly.

+ * This class contains setters and getters for the parts of the URI.
+ * The <code>getXyz</code>/<code>setXyz</code> methods return the decoded part
+ * -- so<code>goog.Uri.parse('/foo%20bar').getPath()</code> will return the
+ * decoded path, <code>/foo bar</code>.
+ *
+ * Reserved characters (see RFC 3986 section 2.2) can be present in
+ * their percent-encoded form in scheme, domain, and path URI components and
+ * will not be auto-decoded. For example:
+ * <code>goog.Uri.parse('rel%61tive/path%2fto/resource').getPath()</code> will
+ * return <code>relative/path%2fto/resource</code>.
+ *
+ * The constructor accepts an optional unparsed, raw URI string. The parser
+ * is relaxed, so special characters that aren't escaped but don't cause
+ * ambiguities will not cause parse failures.
+ *
+ * All setters return <code>this</code> and so may be chained, a la
+ * <code>goog.Uri.parse('/foo').setFragment('part').toString()</code>.
+ *
+ * @param {*=} opt_uri Optional string URI to parse

+/**
+ * @fileoverview Simple utilities for dealing with URI strings.
+ *
+ * This is intended to be a lightweight alternative to constructing goog.Uri
+ * objects. Whereas goog.Uri adds several kilobytes to the binary regardless
+ * of how much of its functionality you use, this is designed to be a set of
+ * mostly-independent utilities so that the compiler includes only what is
+ * necessary for the task. Estimated savings of porting is 5k pre-gzip and
+ * 1.5k post-gzip. To ensure the savings remain, future developers should
+ * avoid adding new functionality to existing functions, but instead create
+ * new ones and factor out shared code.
+ *
+ * Many of these utilities have limited functionality, tailored to common
+ * cases. The query parameter utilities assume that the parameter keys are
+ * already encoded, since most keys are compile-time alphanumeric strings. The
+ * query parameter mutation utilities also do not tolerate fragment identifiers.
+ *
+ * By design, these functions can be slower than goog.Uri equivalents.
+ * Repeated calls to some of functions may be quadratic in behavior for IE,
+ * although the effect is somewhat limited given the 2kb limit.
+ *
+ * One advantage of the limited functionality here is that this approach is
+ * less sensitive to differences in URI encodings than goog.Uri, since these
+ * functions operate on strings directly, rather than decoding them and
+ * then re-encoding.
+ *
+ * Uses features of RFC 3986 for parsing/formatting URIs:
+ * http://www.ietf.org/rfc/rfc3986.txt
+ *
+ * @author gboyer@google.com (Garrett Boyer) - The "lightened" design.

+ * A regular expression for breaking a URI into its component parts.
+ *
+ * {@link http://www.ietf.org/rfc/rfc3986.txt} says in Appendix B
+ * 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
