Initializing help system before first use

# cp_save_state

Purpose
Save a marker in the CP solver stack to enable restoration of the domains of decision variables at a later stage, e.g., for performing infeasibility analysis.
Synopsis
`procedure cp_save_state`
Example
The following example shows how to save the state of a constraint system:

    ...     ! definition of constraints
    ...
    cp_save_state
    if (not cp_propagate) then
      cp_restore_state
      writeln("Problem is infeasible")
      cp_infeas_analysis
      exit(0)
    end-if
    cp_restore_state
    ...     ! problem solving
