Changeset 9852 for branches/HeuristicLab.ReingoldTilfordTreeLayout/HeuristicLab.Encodings.SymbolicExpressionTreeEncoding/3.4/Interfaces

#2076: Created new branch as the old one was crashing subversion:

• Restructured branch contents, created HeuristicLab.TreeLayout solution.
• Merged HeuristicLab.Encodings.SymbolicExpressionTreeEncoding and HeuristicLab.Encodings.SymbolicExpressionTreeEncoding.Views from the trunk
• Renamed TreeLayout to ReingoldTilfordLayoutEngine and moved it to HeuristicLab.Encodings.SymbolicExpressionTreeEncoding/LayoutEngines
• Added SymbolicExpressionTreeLatexFormatter and modified the SymbolicExpressionTreeChart to allow the export of tree in pgf/latex format (using the formatter and the layout engine).
