Alpha release of version 0.0.12

Major upgrade and improvements to documentation have been made. Whilst doing so, the documentation was updated to allow for a slightly clearer twine structure (improved key names and a reconciled approach to treatment of files/values for inputs/configuration).

Neither twined nor the dependent octue-sdk library are up to date with these proposed changes yet, this alpha release allows review of the latest documentation and thinking about the twine spec.

Examples were also added, for use as demonstrators in a development project.
