      Load a Qt Designer .ui file and return an instance of the user interface.
  
      uifile is a file name or file-like object containing the .ui file.
      baseinstance is an optional instance of the Qt base class.  If specified
      then the user interface is created in it.  Otherwise a new instance of the
      base class is automatically created.
      package is the optional package which is used as the base for any relative
      imports of custom widgets.
      resource_suffix is the suffix appended to the basename of any resource file
      specified in the .ui file to create the name of the Python module generated
      from the resource file by pyrcc4.  The default is '_rc', i.e. if the .ui
      file specified a resource file called foo.qrc then the corresponding Python
      module is foo_rc.
