Now validated job-definition against schema

• Schema taken from data-manager
• In theory DM no longer needs to validate the schema but it should do for the time-being

Wipes on success

• Wipes test directory in success (unless --keep-results)
• Cannot --wipe and --keep-results

Supports 'ignore:' test declaration

Just add ignore: to a test (it needs no value)

Fixes test with multi-line commands

• Inputs now require an explicit prefix (enforced)
• Introduces a '--wipe'
• --dry-run and --keep-results can now be used together
• test data can now use sub-directories

Now checks CWD

• Checks cwd for .yamllint and data-manager directory
• Doc tweak

Fixed lint handling

• Linter was broken
• Also fixes --dry-run, which was running checks

Now executes yamllint

• Used the target repo's .yamllint file
• Feature can be avoided with --skip-lint

Initial logic

• Initial prototype 'jote' utility that can be used against the virtual screening repo
• Acts on tests documented in the Job description YAML
