Finished updating the custom filters and custom widgets with the new API.
Created bridge code for filters for ComparisonInputs widgets and AxisAngles widgets.
Added more API to FilterWidgetCodeGen to display more parameters inside the filter widgets in the pipeline of the DREAM3D GUI.
removing debug statements
Initial working version of properly writing a pipeline to a DREAM3D file and then being able to extract that pipeline back to the DREAM3D gui and also append that pipeline to another pipeline in the case where the DREAM3D file is read at the start of a pipeline and during the pipeline a write DREAM3D filter is used. Also have a complete Example plugin that has one of every type of Input Widget available as an example. closes #45. closes #47. closes #44
