New SSN requirement: programming/tasking and actuation

Hi there!

Action-196 <https://www.w3.org/2015/spatial/track/actions/196> is about
adding two requirements for the SSN deliverable to the UC&R document. This
is a proposal for the second of those two requirements. This
<https://lists.w3.org/Archives/Public/public-sdw-wg/2016Sep/0022.html> is
the thread for the other one.

I propose to add the following requirement:

*Tasking/programming and actuation.*

*Requirement: *It should be possible to model tasking/programming and
actuation of sensing devices.

The terms tasking and programming are taken to mean the same: the assembly
and transmission of instructions intended to control the behaviour of a
sensing device. Actuation of a sensing device is its ability to change
something in its environment upon receiving a signal.
*Related deliverable: *SSN
*Related use cases:*

Again I should note that so far I have tried the existing pool of use cases
to support this requirement. If necessary, we could add use case from the
set of use cases that underpinned the first version of SSN
<https://www.w3.org/2005/Incubator/ssn/XGR-ssn-20110628/#Motivating_Use_cases_.28Sensor_Web_and_Sensor_Networks.29>.
My thought was that there are many use cases already, so if a new use case
does not bring unique requirements to the table we should not add it.

If you have any comments or suggestions, please make them known. The aim is
to include this new requirement in the UCR version that will be frozen
before TPAC, so there is not much time.
