/* Custom widget areas. 

Usage:
<?php bfa_widget_area([parameters]); ?>

Example: 
<?php bfa_widget_area('name=My widget area&cells=4&align=1&align_2=9&align_3=7&width_4=700&before_widget=<div id="%1$s" class="header-widget %2$s">&after_widget=</div>'); ?>

Can be used anywhere in templates, and in theme option text areas that allow usage of PHP code.

Available paramaters:

Mandatory:
name					Name under which all cells of this widget area will be listed at Site Admin -> Appearance -> Widgets
							A widget area with 3 cells and a name of "My widget area" creates 3 widget cells which appear as
							"My widget area 1", "My widget area 2" and "My widget area 3", 
							with the CSS ID's "my_widget_area_1", "my_widget_area_2" and "my_widget_area_3". 
						
Optional:
cells						Amount of (table) cells. Each cell is a new widget area. Default: 1
align						Default alignment for all cells. Default: 2 (= center top). 1 = center middle, 2 = center top, 3 = right top, 4 = right middle, 
							5 = right bottom, 6 = center bottom, 7 = left bottom, 8 = left middle, 9 = left top.
align_1					Alignment for cell 1: align_2, align_3 ... Non-specified cells get the default value of "align", which, if not defined, is 2 (= center top).
width_1				Width of cell 1: width_1, width_2, width_3 ... Non-specified cells get a equal share of the remaining width of the whole table
							containing all the widget area cells.
before_widget		HTML before each widget in any cell of this widget area. Default:  <div id="%1$s" class="widget %2$s">
after_widget		HMTL after each widget ... Default: </div>
before_title			HTML before the title of each widget in any cell of this widget area: Default: <div class="widget-title"><h3>
after_title			HMTL after the title ... Default: </h3></div>
