- Conversion made it's own method
- Conversion only run once on addition of provider
- Loading of composite skills from provider still needs to be thought out

- rename methods from loadSkills to loadCompositeSkills
- add loadCompositeSkillsOfProvider(name)
- Remove deleted skills from load

changes:
- added type enum
- contextList sent as vector over ice (no formatting)

changes:
- executions are stored as unique pointers
- replaced usage of raw pointers with smart pointers
- added mutex and locks for composit and merger executor

does compile but not tested

steps where taken:
* nodes as unique ptr
* skill no copy constr.
* skill returns as observer ptr
