This module allows programmers to work with the most general class of CAM
User Function objects. It is used to query and set the parameters of most
UF CAM objects and to control the inheritance of parameter values.

It is also used to perform generic functions such as rename and duplicate.
Most UF CAM objects, (e.g., UF_SETUP, UF_OPER, UF_NCGROUP), inherit from
UF_PARAM. Due to module function inheritance, all the functions of
UF_PARAM can be applied to any object of any module that belongs to the
hierarchy rooted at UF_PARAM. This hierarchy can be found in <>.
