Twined

This release provides improved validation (a set of minor fixes enabling the octue-sdk-python 0.1.4 release) as well as a major refactor of tests for improved speed and clarity (the refactor also serving to welcome our new contributor cortadocodes into the world of twined).

Major upgrade and improvements to documentation and twine structure.

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).

Comprehensive validation of credentials, children and manifests was added, as well as various helper methods and properties based on need in the octue-sdk-python library (which has a number of thorough use cases for the Twine class.

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

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.

Minor release just to add a pypi badge so users can navigate to the installable repo from GitHub.

Basic validation now undertaken for all strands:
- Added credential parser and checker
- Added children parser and checker
- Added manifests parser and checker (very basic)

Updated schema for manifests:
- kind now enumerated with the only option that currently makes sense, and default provided to remove the pain

Improved error logging:
- validation errors now contain a printout of what the error is. Helpful!
