Detailed Description

This class is used to define standard modifications to a Process.
An instance of this class is declared to denote a specific modification,e.g. era2017 could
reconfigure items in a process to match our expectation of running in 2017. Once declared,
these Modifier instances are imported into a configuration and items which need to be modified
are then associated with the Modifier and with the action to do the modification.
The registered modifications will only occur if the Modifier was passed to 
the cms.Process' constructor.

This is used to create a ProcessModifer which can perform actions on the process as a whole.
   This takes as argument a callable object (e.g. function) which takes as its sole argument an instance of Process.
   In order to work, the value returned from this function must be assigned to a uniquely named variable.

This is used to register an action to be performed on the specific object. Two different forms are allowed
Form 1: A callable object (e.g. function) can be passed as the second. This callable object is expected to take one argument
which will be the object passed in as the first argument.
Form 2: A list of parameter name, value pairs can be passed
