+// Autocompleter.Base handles all the autocompletion functionality
+// that's independent of the data source for autocompletion. This
+// includes drawing the autocompletion menu, observing keyboard
+// and mouse events, and similar.
+//
+// Specific autocompleters need to provide, at the very least,
+// a getUpdatedChoices function that will be invoked every time
+// the text inside the monitored textbox changes. This method
+// should get the text for which to provide autocompletion by
+// invoking this.getToken(), NOT by directly accessing
+// this.element.value. This is to allow incremental tokenized
+// autocompletion. Specific auto-completion logic (AJAX, etc)
+// belongs in getUpdatedChoices.
+//
+// Tokenized incremental autocompletion is enabled automatically
+// when an autocompleter is instantiated with the 'tokens' option
+// in the options parameter, e.g.:
+// new Ajax.Autocompleter('id','upd', '/url/', { tokens: ',' });
+// will incrementally autocomplete with a comma as the token.
+// Additionally, ',' in the above example can be replaced with
+// a token array, e.g. { tokens: [',', '\n'] } which
+// enables autocompletion on multiple tokens. This is most
+// useful when one of the tokens is \n (a newline), as it
+// allows smart autocompletion after linebreaks.

+// 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

+//
+// - 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'

+ * <h3><a name="locators"></a>Element Locators</h3>
+ * <p>
+ * Element Locators tell Selenium which HTML element a command refers to.
+ * The format of a locator is:</p>
+ * <blockquote>
+ * <em>locatorType</em><strong>=</strong><em>argument</em>
+ * </blockquote>
+ *
+ * <p>
+ * We support the following strategies for locating elements:
+ * </p>
+ *
+ * <ul>
+ * <li><strong>identifier</strong>=<em>id</em>:
+ * Select the element with the specified @id attribute. If no match is
+ * found, select the first element whose @name attribute is <em>id</em>.
+ * (This is normally the default; see below.)</li>
+ * <li><strong>id</strong>=<em>id</em>:
+ * Select the element with the specified @id attribute.</li>
+ *
+ * <li><strong>name</strong>=<em>name</em>:
+ * Select the first element with the specified @name attribute.
+ * <ul class="first last simple">
+ * <li>username</li>
+ * <li>name=username</li>
+ * </ul>
+ *
+ * <p>The name may optionally be followed by one or more <em>element-filters</em>, separated from the name by whitespace. If the <em>filterType</em> is not specified, <strong>value</strong> is assumed.</p>
+ *
+ * <ul class="first last simple">
+ * <li>name=flavour value=chocolate</li>
+ * </ul>
+ * </li>
+ * <li><strong>dom</strong>=<em>javascriptExpression</em>:
+ *
+ * Find an element by evaluating the specified string. This allows you to traverse the HTML Document Object
+ * Model using JavaScript. Note that you must not return a value in this string; simply make it the last expression in the block.
+ * <ul class="first last simple">
+ * <li>dom=document.forms['myForm'].myDropdown</li>
+ * <li>dom=document.images[56]</li>
+ * <li>dom=function foo() { return document.links[1]; }; foo();</li>
+ * </ul>
+ *
+ * </li>
+ *
+ * <li><strong>xpath</strong>=<em>xpathExpression</em>:
+ * Locate an element using an XPath expression.
+ * <ul class="first last simple">
+ * <li>xpath=//img[@alt='The image alt text']</li>
+ * <li>xpath=//table[@id='table1']//tr[4]/td[2]</li>
+ * <li>xpath=//a[contains(@href,'#id1')]</li>
+ * <li>xpath=//a[contains(@href,'#id1')]/@class</li>
+ * <li>xpath=(//table[@class='stylee'])//th[text()='theHeaderText']/../td</li>
+ * <li>xpath=//input[@name='name2' and @value='yes']</li>
+ * <li>xpath=//*[text()="right"]</li>
+ *
+ * </ul>
+ * </li>
+ * <li><strong>link</strong>=<em>textPattern</em>:
+ * Select the link (anchor) element which contains text matching the
+ * specified <em>pattern</em>.
+ * <ul class="first last simple">
