ENH: Initial commit of new runTimePostProcessing function object

- Allows generation of images (currently PNG files) during the run - ... or afterwards by invoking the execFlowFunctionObjects utility - Wrapper around VTK functionality - Support for objects: - text - points (glyphs: sphere, arrow) - lines (tubes) - surfaces (wireframe, shaded, combination) - Colour using: - user-defined - field values (several colour maps availale) - For image sequences: - dynamic views (camera movement) - objects can appear/disappear using opacity - Building - VTK dependency v6+ - satisfied using ParaView from ThirdParty directory - or separate VTK installation
