def normalize(self, bounds, units, inplace=False):
""" Normalize the angle to be within the bounds specified. If inplace==True,
this replace the internal values, otherwise it returns a new Angle object.
Parameters
----------
bounds : tuple
A tuple with 2 values (low, hi) where this is the range you would like
to normalize the angle to. For example, if you have an angle value of
752.1834 but you want it to be within the range -180 -> +180, you can
specifiy `Angle.normalize((-180, 180), units="degrees")`.
