Change README to state Boost is not a requirement #5
Description
Currently there is this text:
... requires Boost with support for version 4 of the Boost.Thread interface
However this is not the case, as the standard library is used by default as of 872fc6d. Better wording would be to mention Boost can be used in place of the standard library.
As as user I would find this beneficial looking for a lightweight thread pool that does not tie into Boost (as I was a few days ago) and might not have looked into the library if I read the Boost portion.
