 Destructor.

 Init the tree.

 Called when a new tree is loaded.

 Executed by the client before processing.

 Processes a single variable from an entry.

 Executed for each entry.

 Executed by each slave after the processing has finished,
 before returning the results to the client.

 Executed by the client after getting the processing retults.

 Delete internal buffers.

 Sets the error status.

 Compiles each variable from fTreeDrawArgsParser for the tree fTree.
 Return kFALSE if any of the variable is not compilable.
