 34 Embedded SVG-edit API
 35 
 36 General usage:
 37 - Have an iframe somewhere pointing to a version of svg-edit > r1000
 38 - Initialize the magic with:
 39 var svgCanvas = new embedded_svg_edit(window.frames['svgedit']);
 40 - Pass functions in this format:
 41 svgCanvas.setSvgString("string")
 42 - Or if a callback is needed:
 43 svgCanvas.setSvgString("string")(function(data, error){
 44  if(error){
 45  //there was an error
 46  }else{
 47  //handle data
 48  }
 49 })
 50 
 51 Everything is done with the same API as the real svg-edit, 
 52 and all documentation is unchanged. The only difference is
 53 when handling returns, the callback notation is used instead. 
 54 
 55 var blah = new embedded_svg_edit(window.frames['svgedit']);
 56 blah.clearSelection("woot","blah",1337,[1,2,3,4,5,"moo"],-42,{a: "tree",b:6, c: 9})(function(){console.log("GET DATA",arguments)})
