Release v1.2

Add the license into the code. The license must be provided with the source code in some way. It is much easier for this to be within the single header file.

Release v1.1

Removal of iostream

iostream was included by the header for debugging purposes, and this was included in the previous 1.0 release.

This new release does not include iostream.

Release v1.0 | Initial Release

Initial release of Pooler with the Unlicense.
