VDB-919 Generalise converter (#152)
* Generalise transformer stack to use InsertionModel

* Add tests for event repository

* Restrict accepted values in InsertionModel

* Add call to repository.SetDB

* Improve error propagation/clarity on GetABI()

* Remove maker references in example

* Please golint

* refactor rollback error handling in repository

* Cleaner errors in repository, refactor tests
