[Ndn-interest] Parameter, argument passing in Interest name

[Moreno Ambrosin]

Hi Anil,

 The idea is that the Producer should be aware that the interest name
contains the parameters (e.g.,
/a/content/name/{id1}/{value1}/{id2}/{value2}/...).
Once received the interest, the Producer will parse the name specified in
the interest and extract the data.
