Fork with extensions for import / export (eg Graphviz)

[Almerxsese]

Hello

Here is a fork with extensions for import / export (eg Graphviz). Currently there is only 1 "export filter" which generates a .dot file from a xmind map. Then this .dot file is given as input to the "twopi.exe" tool (one of the tools provided by Graphviz) which generates a visual representation of the mindmap in a pdf file.
