filling holes in process script. new version:

1. requirements added as github issues by maintainer
2. maintainer solicits estimation from developer
3. developer issues delivery date and itemized hourly estimation budgeting for i) feature addition or fix, ii) unit tests, iii) integration tests, iv) code review and v) code review changes
4. maintainer approves estimation from developer
5. developer branches and creates wip pull request
6. developer proposes new delivery date and itemized hourly estimation of obstacles posing risk to initially negotiated estimation
7. maintainer eliminates obstacles posing risk to initially negotiated estimation
8. maintainer accepts or rejects new estimation
9. developer finishes pull request
10. unless negotiated, developer maintains or increases code coverage
11. developer requests code review from maintainer
12. developer adds changes required during code review
13. all tests pass before or on accepted delivery date
14. maintainer merges pull request
15. maintainer pays developer

please comment approval or rejection in billing tool

if rejecting, please close wip pull request
else, begin from #6 by posting comment here

process script aims to protect maintainer from management costs
