MasterKey searching facilities. By placing `<div>`s with well-known
MKWS classes in any HTML page, the various components of an application

Go ahead, try it! Simply put the above in a file (e.g index.html),
-drop it into a folder accessible with an ordinary web-server (e.g Apache)
-and load it in your web browser (and no, usually, you can't just load the file
-directly from disk as some browsers, e.g Chrome, won't allow storing cookies).

contains all the JavaScript needed by the widget-set.
Second, within the HTML body, `<div>` elements with special IDs that
begin `mkws` can be provided. These are filled in by the MKWS code,
and provide the components of the searching UI. The very simple
-application above has only two such components: a search box and a
-results area. But more are supported. The main `<div>`s are:

sorting facilities, etc.

* `mkwsSwitch` -- provides links to switch between a view of the
result records and of the targets that provide them. Only

mostly for fault diagnosis rather than for end-users.

To see all of these working together, just put them all into the HTML
`<body>` like so:
<div id="mkwsTargets"></div>
<div id="mkwsStat"></div>

Configuration
=============
Many aspects of the behaviour of MKWS can be modified by setting
-parameters into the `mkws_config` object. **This must be done *before*
-including the MKWS JavaScript** so that when that code is executed it
-can refer to the configuration values. So the HTML header looks like

etc., customised layouts may wish to treat each of these components
separately. In this case, `mkwsResults` can be omitted, and the
-following lower-level components provided instead:

* `mkwsTermlists` -- provides the facets
Customisation of MKWS searching widgets can also be achieved by
overriding the styles set in the toolkit's CSS stylesheet. The default
-styles can be inspected in `mkws.css` and overridden in any
+styles can be inspected in [mkws.css](mkws.css)
+and overridden in any
styles that appears later in the HTML than that file. At the simplest
level, this might just mean changing fonts, sizes and colours, but
more fundamental changes are also possible.

to style each `<div>` with class `term` but only when it occurs inside an
element with ID `#mkwsTermlists`, so as to avoid inadvertently styling other
elements using the same class in the non-MKWS parts of the page.
