def make_prior(self, attribute_name):
"""
Returns a prior for an attribute of a class with a given name. The prior is
created by searching the default prior config for the attribute.
Entries in configuration with a u become uniform priors; with a g become
gaussian priors; with a c become instances.
If prior configuration for a given attribute is not specified in the
configuration for a class then the configuration corresponding to the parents
of that class is searched. If no configuration can be found then a prior
exception is raised.
Parameters
----------
attribute_name: str
The name of the attribute for which a prior is created
Returns
-------
prior: p.Prior
A prior
Raises
------
exc.PriorException
If no configuration can be found
