## The zicreg S4 Class

### Description

Note that `zicreg`

objects are, in general, S3. However,
this S4 class is defined for compatability with `texreg`

.
Interaction with `zicreg`

objects should generally use S3 syntax, but the below
objects have the same name in both the S3 and S4 objects (but are in a list for S3).
