Try using an Array trait with buckets for scene management

[Robert42]

The classes glrt::ArrayBucketTraits_VariableNumberOfBuckets and glrt::ArrayBucketTraits_FixedNumberOfBuckets are meant to be used as traits for an array. See https://github.com/Robert42/gl-research-toolkit/blob/c20fe3c43e2260c6610f7f601ac694681160d62d/gl-research-toolkit/core/include/glrt/toolkit/array-bucket-traits.h

• Thought for automagically keep the array correct sorted when adding new elements/removing
• [ ] continue implementing
• [ ] profile, whether there's a significant speed up in oppisite to just update the whole buffer at once
  • [ ] Solution: Objects have different persistentness. This way no time is wasted in moving the persistent objects in the buffer (what about LODs?).
  • Persistent: never gonna be deleted
  • deleted seldom
  • deleted shortly after being created

too much effort for a suboptiomal solution (possibly shifting the whole array)

An own Array class is risky eneough. It should do only one thing
