/**
 * Dropdown-like field that allows you to select an item from a hierarchical
 * AJAX-expandable tree.
 *
 * Creates a field which opens a dropdown (actually a div via javascript
 * included for you) which contains a tree with the ability to select a singular
 * item for the value of the field. This field has the ability to store one-to-one
 * joins related to hierarchy or a hierarchy based filter.
 *
 * **Note:** your source object must use an implementation of hierarchy for this
 * field to generate the tree correctly, e.g. {@link Group}, {@link SiteTree} etc.
 *
 * All operations are carried out through javascript and provides no fallback
 * to non JS.
 *
 * <b>Usage</b>.
 *
 * <code>
 * static $has_one = array(
 *   'RightContent' => 'SiteTree'
 * );
 *
 * function getCMSFields() {
 * ...
 * $treedropdownfield = new TreeDropdownField("RightContentID", "Choose a page to show on the right:", "SiteTree");
 * ..
 * }
 * </code>
 *
 * This will generate a tree allowing the user to expand and contract subsections
 * to find the appropriate page to save to the field.
 *
 * Caution: The form field does not include any JavaScript or CSS when used outside of the CMS context,
 * since the required frontend dependencies are included through CMS bundling.
 *
 * @see TreeMultiselectField for the same implementation allowing multiple selections
 * @see DropdownField for a simple dropdown field.
 * @see CheckboxSetField for multiple selections through checkboxes.
 * @see OptionsetField for single selections via radiobuttons.
