adjusted merge fails adjusted to my previous (not committed) changes; my other changes are coming soon
added yaml classes from Albert to yaml model project; also adjusted package structure to main project
updated ignore files
renamed interfaces according to naming convention; made use of YAMLElement instead of YamlRootElement (because I added the YAML classes to the model project); created tests and added test resources
removed yaml root because it was in the wrong package (i changed the package names)
