ParaView reader module(s) need upgrade

The custom properties panels are derived from a pqAutoGeneratedObjectPanel which is not supported with paraview-5.1 and newer (http://www.paraview.org/ParaView3/Doc/Nightly/www/cxx-doc/MajorAPIChanges.html). Instead need to use a pqPropertyWidget as outlined:

• http://www.paraview.org/Wiki/Plugin_HowTo#Adding_Customizations_for_Properties_Panel
• http://www.paraview.org/Wiki/ParaView/Properties_Panel

Need to check details about the current method of integrating.
