Detailed Description

Enables the connection and sending of binary and text data through a socket both with and without event-loops.

After construction, you need to connect to a host on a port. If you choose not to wait then (dis-)connecting only fails if it is already in progress.

Strings are transferred without trailing '\0', but with a leading integer for the size.
