Detailed Description

An asio TCP socket with an associated streambuf buffer for receiving lines of text, as well as string buffers for sending responses.

Used for communicating with MHA TCP clients. The life time of the connection objects is managed with shared pointers registered together with callbacks in the asio event loop. This is a common idiom in asio. To support this, we inherit from enable_shared_from_this which is also common in code that uses asio.
