Finite capacity for a specified horizon

Finite and infinite capacity planning can be mixed in a planning session in different ways: they can be applied distinctly to different
resources (as told in another post of this blog) or they can also be combined to the same resource (workcenter, tools or other facilities). In other words, it is often convenient
to set the finite capacity constraint to a resource over a specified horizon from the current date and leave infinite capacity beyond that horizon.
This way we can model the case when we cannot change capacity in the short run but we can acquire additional resources or capacity in the medium/long period. Is trivial to setup this in Cowry.
