/** This plugin enables to import a graph coded with in dot format
*
* File format:
* [ http://www.research.att.com/sw/tools/graphviz/ ]
*
* First (quick) support of the AT&T DOT language
* - main graph entities are extracted (node/edges)
* - subgraphs are not already supported
* - several attributes (node & edge) are supported
* - based on a modified grammar file available with the graphviz software
* - this parser can be largely optimized ...
