-// The local array autocompleter. Used when you'd prefer to
-// inject an array of autocompletion options into the page, rather
-// than sending out Ajax queries, which can be quite slow sometimes.
-//
-// The constructor takes four parameters. The first two are, as usual,
-// the id of the monitored textbox, and id of the autocompletion menu.
-// The third is the array you want to autocomplete from, and the fourth
-// is the options block.
-//
-// Extra local autocompletion options:
-// - choices - How many autocompletion choices to offer
-//
-// - partialSearch - If false, the autocompleter will match entered
-// text only at the beginning of strings in the
-// autocomplete array. Defaults to true, which will
-// match text at the beginning of any *word* in the
-// strings in the autocomplete array. If you want to
-// search anywhere in the string, additionally set
-// the option fullSearch to true (default: off).
-//
-// - fullSsearch - Search anywhere in autocomplete array strings.
-//
-// - partialChars - How many characters to enter before triggering
-// a partial match (unlike minChars, which defines
-// how many characters are required to do any match
-// at all). Defaults to 2.
-//
-// - ignoreCase - Whether to ignore case when autocompleting.
-// Defaults to true.
-//
-// It's possible to pass in a custom function as the 'selector'
-// option, if you prefer to write your own autocompletion logic.
-// In that case, the other options above will not apply unless
-// you support them.
