* \brief Theme based on the Twitter Bootstrap CSS framework.
*
* This theme implements support for building a %Wt web application
* that uses Twitter Bootstrap as a theme for its (layout and)
* styling. The theme comes with CSS from Bootstrap version 2.2.2 or
* version 3.1. Only the CSS components of twitter bootstrap are used,
* but not the JavaScript (i.e. the functional parts), since the
* functionality is already built-in to the widgets from the library.
*
* Using this theme, various widgets provided by the library are
* rendered using markup that is compatible with Twitter
* Bootstrap. The bootstrap theme is also extended with a proper
* (compatible) styling of widgets for which bootstrap does not
* provide styling (table views, tree views, sliders, etc...).
*
* By default, the theme will use CSS resources that are shipped
* together with the %Wt distribution, but since the Twitter Bootstrap
* CSS API is a popular API for custom themes, you can easily replace the
* CSS with custom-built CSS (by reimplementing styleSheets()).
*
* Although this theme facilitates the use of Twitter Bootstrap with
* %Wt, it is still important to understand how Bootstrap expects
* markup to be, especially related to layout using its grid system, for
* which we refer to the official bootstrap documentation, see
* http://getbootstrap.com

* change, the version has a big impact on how how the markup is
* done for various widgets.
