#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).
