/*
Embedded SVG-edit API

General usage:
- Have an iframe somewhere pointing to a version of svg-edit > r1000
- Initialize the magic with:
var svgCanvas = new embedded_svg_edit(window.frames['svgedit']);
- Pass functions in this format:
svgCanvas.setSvgString("string")
- Or if a callback is needed:
svgCanvas.setSvgString("string")(function(data, error){
  if(error){
    //there was an error
  }else{
    //handle data
  }
})

Everything is done with the same API as the real svg-edit, 
and all documentation is unchanged. The only difference is
when handling returns, the callback notation is used instead. 

var blah = new embedded_svg_edit(window.frames['svgedit']);
blah.clearSelection("woot","blah",1337,[1,2,3,4,5,"moo"],-42,{a: "tree",b:6, c: 9})(function(){console.log("GET DATA",arguments)})
