/**
 * Returns a collation-based scanner.
 *
 * Only primary differences are treated as significant.  This means that case
 * differences, accent differences, alternate spellings of the same letter
 * (e.g., ae and a-umlaut in German), ignorable characters, etc. are ignored in
 * matching the text.  In many cases, numerals will be accepted in place of words
 * or phrases as well.
 *
 * For example, all of the following will correctly parse as 255 in English in
 * lenient-parse mode:
 * <br>"two hundred fifty-five"
 * <br>"two hundred fifty five"
 * <br>"TWO HUNDRED FIFTY-FIVE"
 * <br>"twohundredfiftyfive"
 * <br>"2 hundred fifty-5"
 *
 * The Collator used is determined by the locale that was
 * passed to this object on construction.  The description passed to this object
 * on construction may supply additional collation rules that are appended to the
 * end of the default collator for the locale, enabling additional equivalences
 * (such as adding more ignorable characters or permitting spelled-out version of
 * symbols; see the demo program for examples).
 *
 * It's important to emphasize that even strict parsing is relatively lenient: it
 * will accept some text that it won't produce as output.  In English, for example,
 * it will correctly parse "two hundred zero" and "fifteen hundred".
