Animates a "loading" icon that can be used by any Qt object that
has the C{setIcon} method.

Example:

def startTask(self):

    self.button = QtWidgets.QPushButton('Button')

    self.loading_icon = bwidgets.LoadingIcon(self)
    self.loading_icon.startLoading(self.button)

    self.launchTask()
    
def taskCallback(self):

    self.loading_icon.stopLoading()
