/**

 * Build Page Layouts

 *

 * Unlike the Panels layouts which hold CSS in their data array the Page layout

 * plugins each include a unique CSS builder function. This is required because

 * page layouts are all bespoke and can accept arbitrary user input for the

 * sidebar widths and must support three value units - pixles, em's and

 * percentages.  In other words building a one-size-fits-all builder function

 * would be overly complex and its far more flexible for themers to be able to

 * define thier own.

 *

 * As values come in from the submit function they are dispatched to the right

 * builder function.

 *

 * @param $method, tells the function which layout builder function to call.

 * @param $sidebar_first, an arbitrary numeric value.

 * @param $sidebar_second, an arbitrary numeric value.

 * @param $sidebar_unit, one of px, em or %.

 * @param $theme_name, the active theme.

 *

 * @see three_col_grail_layout() for an example of a builder function with docs.
