/**
 * \brief Smarty {tikimodule}{/tikimodule} block handler
 *
 * To make a module it is enough to place smth like following
 * into corresponding mod-name.tpl file:
 * \code
 *  {tikimodule name="module_name" title="Module title"}
 *    <!-- module Smarty/HTML code here -->
 *  {/tikimodule}
 * \endcode
 *
 * This block may (can) use 2 Smarty templates:
 *  1) module.tpl = usual template to generate module look-n-feel
 *  2) module-error.tpl = to generate diagnostic error message about
 *     incorrect {tikimodule} parameters
 *
 * It also supports the param flip="y" to make this module flippable.
 * flip="n" is the default.
 * and the param decorations="n" to suppress module decorations
 * decorations="y" is the default.

\Note
error was used only in case the name was not there.
I fixed that error case. -- mose
