* Returns [[xmlnode]] if created successfully, ''false'' otherwise.

==Example==
<section name="Client" class="client" show="true">

loadstring(exports.dgs:dgsImportFunction())() -- load dgs functions using loadstring.

local svg = dgsCreateSVG(500,500) -- Create the SVG . 
local svgDoc = dgsSVGGetDocument(svg) -- Get the SVG Document so you can modify it .
local rect = dgsSVGCreateNode(svgDoc,"rect",50,50) -- Create SVG node with rect type.
