* Moved Generator.cs into Editor folder under AtomsEditor.asmdef
Generator.cs must not be outside of the Editor Assembly Definition because it uses UnityEditor and thus would prevent games from building
* - cleaned up unused imports
- fixed a potential bug in Templating.cs because IndexOf is culture specific
- at least warnings in Rider are now eliminated
- cleaned up the logic of Templating.cs
- the while condition had never changed, it contained a redundant true
- using an early return if the list is null
* Replaced ResolveConditionals in Templating.cs to allow nested IF-blocks
fixed typos
