/**
* Source for the Tulip file format (TLP).
*
* TLP files begins with :
*
* <pre>
* (tlp "2.0"
* ; file content
* )
* </pre>
*
* Some meta informations can be done :
*
* <pre>
* (tlp "2.0"
*   (author "author name")
*  (date "...")
*  (comments "...")
*  ...
* )
* </pre>
*
* Node indexes are integer. They can be declared in a "nodes" tag :
*
* <pre>
*   (tlp "2.0"
*     (nodes 1 2 3)
*    (edge 1 1 2)
*    (edge 2 1 3)
*    (edge 3 2 3)
*   )
* </pre>
*
* Then edge can be defined with an int index followed by the index of the
* source node and the target nodes.
*
* Clusters can be created with an index and a name:
* <pre>
*   (tlp "2.0"
*     (nodes 1 2 3)
*    (edge 1 1 2)
*    (edge 2 1 3)
*    (edge 3 2 3)
*    (cluster 1 "cluster name"
*      (nodes 1 3)
*      (edges 2)
*    )
*   )
* </pre>
*
* Cluster 0 is the root graph.
*
* Properties can be applied to cluster:
* <pre>
*   (tlp "2.0"
*     (nodes 1 2 3)
*    (edge 1 1 2)
*    (edge 2 1 3)
*    (edge 3 2 3)
*    (property cluster_id type "name"
*      (default "node_default" "edge_default")
*      (node node_id "value")
*      (edge edge_id "value")
*    )
*   )
* </pre>
*
* Type of properties can be one of :
* <ul>
* <li>bool</li>
* <li>double</li>
* <li>int</li>
* <li>string</li>
* <li>color</li>
* <li>layout</li>
* <li>size</li>
* </ul>
