/**
* Concrete class for demonstrating language sensitive collation.
* The following is the instruction on how to run the collation demo.
* <p>
* ===================
* <H3>Customization</H3>
* You can produce a new collation by adding to or changing an existing
* one.
* <H4>To show...</H4>
* <BLOCKQUOTE>You can modify an existing collation to show how this works.
* By adding items at the end of a collation you override earlier
* information.
* Watch how you can make the letter P sort at the end of the
* alphabet.</BLOCKQUOTE>
* <H4>Do...</H4>
* <BLOCKQUOTE>1. Scroll to the end of the Sequence field. After the Z,
* type
* "< p , P". This will put the letter P (with both of its
* case
* variants) at the end of the alphabet. Hit the Set Rule button. This creates
* a new collation with the name "Custom-1" (you could give it a
* different name by typing in the Collator Name field). When you now look
* at the Text field, you will see that you have changed the sequence to put
* <I>Pat</I>
* at the end. (If you did not have Sort Ascending on, click it
* now.)</BLOCKQUOTE>
* <BR>
* Making P sort at the end may not seem terribly useful, but it is used to
* make modifications in the sorting sequence for different languages.
* <H4>To show...</H4>
* <BLOCKQUOTE>For example, you can add CH as a single letter after C, as
* in
* traditional Spanish sorting.</BLOCKQUOTE>
* <H4>Do...</H4>
* <BLOCKQUOTE>Enter in the following after Z; "& C < ch , cH, Ch,
* CH".
* Hit the Set Rule button, type in test words in the Text field (such as
* "czar",
* "churo" and "darn"), and select Sort Ascending to
* see
* the resulting sort order.</BLOCKQUOTE>
* <H4>To show...</H4>
* <BLOCKQUOTE>You can also add other sequences to the collation rules,
* such as sorting symbols with their alphabetic equivalents.</BLOCKQUOTE>
* <H4>Do...</H4>
* <BLOCKQUOTE>1. Scroll to the end of the Sequence field. After the end,
* type the following list (you can just select this text in your browser and
* paste it in, to avoid typing). Now type lines in the Text field with these
* symbols on them, and select Sort Ascending to see the resulting sort
* order.</BLOCKQUOTE>
* <UL>
* <UL>
* <LI>& Asterisk ; *
* <LI>& Question-mark ; ?
* <LI>& Hash-mark ; #
* <LI>& Exclamation-mark ; !
* <LI>& Dollar-sign ; $
* <LI>& Ampersand ; '&';
* </UL>
* </UL>
* <H4>Details</H4>
* If you are an advanced user and interested in trying out more rules,
* here is a brief explanation of how they work. The sequence is a list of
* rules. Each rule is of two forms:
* <UL>
* <LI><modifier>
* <LI><relation> <text-argument>
* <LI><reset> <text-argument>
* </UL>
* <H5>Modifier</H5>
* <BLOCKQUOTE>@ Indicates that accents are sorted backwards, as in
* French</BLOCKQUOTE>
* <H5>Text-argument</H5>
* The text can be any number of characters (if you want to include special
* characters, such as space, use single-quotes around them).
* <H5>Relation</H5>
* The relations are the following:
* <DL>
* <DD>< Greater, as a letter difference (primary)
* <DD>; Greater, as an accent difference (secondary)
* <DD>, Greater, as a case difference (tertiary)
* <DD>= Equal
* <DD>& Reset previous comparison.
* </DL>
* <H5>Reset</H5>
* The "&" is special in that does not put the text-argument
* into the sorting sequence; instead, it indicates that the <I>next</I>
* rule is with respect to where the text-argument <I>would be</I> sorted.
* This sounds more complicated than it is in practice. For example, the
* following are equivalent ways of expressing the same thing:
* <UL>
* <LI>a < b < c
* <LI>a < b & b < c
* <LI>a < c & a < b
* </UL>
* Notice that the order is important, since the subsequent item goes
* <I>immediately</I>
* after the text-argument. The following are <I>not</I> equivalent:
* <UL>
* <LI>a < b & a < c
* <LI>a < c & a < b
* </UL>
* The text-argument must already be present in the sequence, or some
* initial substring of the text-argument must be present. (e.g. "a <
* b& ae < e" is valid since "a" is present in the
* sequence<I>before</I> "ae" is reset). In this latter case,
* "ae"
* is <B><I>not</I></B> entered and treated as a single character; instead,
* "e" is sorted as if it were expanded to two characters:
* "a"
* followed by an "e".<BR>
* This difference appears in natural languages: in traditional Spanish
* "ch"
* is treated as though it <I>contracts</I> to a single character
* (expressed
* as "c < ch < d"), while in traditional German
* "ä"
* (a-umlaut) is treated as though it <I>expands</I> to two characters
* (expressed
* as "a & ae ; ä < b").<BR>
* <H5>Ignorable Characters</H5>
* The first rule must start with a relation (the examples we have used are
* fragments; "a < b" really should be "< a <
* b").
* If, however, the first relation is not "<", then all the
* all
* text-arguments up to the first "<" are ignorable. For
* example,
* ", - < a < b" makes "-" an ignorable
* character,
* as we saw earlier in the word "black-birds".<BR>
* <H5>Accents</H5>
* The Collator automatically normalizes text internally to separate
* accents
* from base characters where possible. So, if you type in an
* "ä"
* (a-umlaut), after you reset the collation you will see
* "a\u0308"
* in the sequence, where \u0308 is the Java syntax for umlaut. The
* demonstration
* program uses this syntax instead of just showing the umlaut since many
* browsers are unable to display the umlaut yet.<BR>
* <H4>Errors</H4>
* The following are errors:
* <UL>
* <LI>Two relations in a row (e.g. "a < , b"
* <LI>Two text arguments in a row (e.g. "a < b c < d")
* <LI>A reset where the text-argument is not already in the sequence
* (e.g."a < b & e < f")
* </UL>
* If you produce one of these errors, then the demonstration will beep at
* you, and select the offending text (note: on some browsers, the
* selection will not appear correctly).
