Added todo list of files with boost references to be removed.
Updated todo list.
Removed obsolete comm_manager
Updated TODO
Removed unneeded boost include.
Removed circular_queue.

This was based on boost::circular_queue, which can not handle
std::unique pointers as of the last check anyway. If we need
a circular queue later, we'll roll our own.
Removed boost references from base_socket.

Updated unit tests as well; passed and ready to use.
Corrected an output typo in the logger unit test.
Added homegrown lexical_cast, but still fails unit test.

We are having problems preserving precison past 4 decimal places,
and determining if the value is a valid int or string. Frankly,
I'm not sure how I was doing that in the past, so some research is
called for.
Much better, but string handling has changed.

Will need to decide if we can ignore the change and alter the
unit test or work harder. I'm not sure included white space is
needed for NRTB, so may bail in the next commit.
Altered test.config to support the unit test changes.
nrtb::confreader boost cleanup complete with behavior changes.

The boost lexical_throws when a requested conversion can't be
accomplished, while stringstream does not. We were using this
functionality to filter in some cases. This was an arbitrary
decision which does not affect most use cases, so we did not
attempt to replicate that functionality. Instead you get the
normal iostream behavior: "duh" would map to 0 for numerics,
and "71.2723" would map to 71 for ints.

Also, to keep it simple on the first whitespace delimited value
after the name is returned by the get and get all transformative
templates. If you want the full value, it's still available by
accessing the internal list.
Boost libs dependency removed from all code. Ready to merge.
Added a confreader unit test for the [] operator.

I decided we needed a test to prove the [] operator works as
advertised given the changes to the get<> and getall<> templates.
Tests completed and ready to go.
