Description:
 def load_ui_type(uifile):
 """Pyside equivalent for the loadUiType function in PyQt. From the PyQt4 documentation: Load a Qt Designer .ui file and return a tuple of the generated form class and the Qt base class. These can then be used to create any number of instances of the user interface without having to parse the .ui file more than once. Note: Pyside lacks the "loadUiType" command, so we have to convert the ui file to py code in-memory first and then execute it in a special frame to retrieve the form_class. Args: uifile (str):
 Absolute path to .ui file Returns: tuple: the generated form class, the Qt base class """
