Update README.md

Mention that svg.absorb.js must be included as a dependency.

[mondalaci]

As it turns out even if I include svg.absorb.js before svg.export.js I get:

 Uncaught TypeError: undefined is not a function

upon exporting.

I'm completely lost at this. I can only use the version of svg.export.js before the svg.absorb.js dependency got introduced.

Can you give me the full error console output from Chrome?

[mondalaci]

Sure. Here you go:

Uncaught TypeError: undefined is not a function [...] layout.html:226
(anonymous function) [...] layout.html:226
j [...] jquery.js:3047
k.fireWith [...] jquery.js:3159
x [...] jquery.js:8183
(anonymous function) [...] jquery.js:8530

layout.html:226 contains:

var exported = layout.exportSvg({whitespace: '    '});
