PolicyGenerator generates a new reference policy module
or updates an existing module based on requested access
in the form of access vectors.
It generates allow rules and optionally module require
statements and reference policy interfaces. By default
only allow rules are generated. The methods .set_gen_refpol
and .set_gen_requires turns on interface generation and
requires generation respectively.
PolicyGenerator can also optionally add comments explaining
why a particular access was allowed based on the audit
messages that generated the access. The access vectors
passed in must have the .audit_msgs field set correctly
and .explain set to SHORT|LONG_EXPLANATION to enable this
feature.
The module created by PolicyGenerator can be passed to
output.ModuleWriter to output a text representation.

existing module.
If the module paramater is not None then access
will be added to the passed in module. Otherwise
a new reference policy module will be created.

Return a string containing a text explanation of
why a policy statement was generated. The string is
commented and wrapped and can be directly inserted
into a policy.
Params:
av - access vector representing the access. Should
have .audit_msgs set appropriately.
verbosity - the amount of explanation provided. Should
be set to NO_EXPLANATION, SHORT_EXPLANATION, or
LONG_EXPLANATION.
Returns:
list of strings - strings explaining the access or an empty
string if verbosity=NO_EXPLANATION or there is not sufficient
information to provide an explanation.
