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)
must rename files with new letters because windows can't check for lower/upper case -.- another commit will follow to rename it back to get upper lower case changed
renaming should be completed
added test utils
added base test class to share common used classes etc
adjusted test classes to test utils and base test; added test class for YamlBeansConverter
changed list to map in YAMLFileRoot to support unique node template names; adjusted tests
Merge pull request #18 from seeebiii/master

Mainly added tests, YAML model classes and renamed interfaces
