/*!
  \class Material_ResourceMgr
  \brief Material properties resources manager.

  This class is used to manage the material properties throughout the application
  in the similar way as QtxResourceMgr does it with application preferences.

  Standard material types are stored in the global application settings files
  (named as SalomeMaterial.xml). User-defined materials are stored in user's home
  directory - in the file .SalomeMaterialrc.

  The Material_ResourceMgr class is used by material properties dialog box
  (GEOMToolsGUI_MaterialPropertiesDlg class).
