[ndnSIM] Evicting a specific item from the content store (nfd::cs::Cs)

Hello all:

Okay, please correct me if I'm wrong:

If I understand this correctly, when you create a custom Policy
subclass/derived class, *the developer *is responsible for creating the
three queues specified in the NFD Developer guide?  (unsolicited, stale,
and fifo)?  So we directly control what stays in the "queues" (std::list)
according the the policy that we can determine.  So the *Policy *maintains
the actual Entries, while the Cs maintains the Table of names?  I noticed
the three queues don't actually live in the cs.cpp or cs.hpp files.

I'm *still * a little confused about the Cs::erase method:  why isn't it
implemented?  How do we "trigger" a removal of an item from the Content
Store (Policy?)
