Class LazySvc<TService>

Helps us create lazy Service objects. It has some special features:

  • It will automatically lazy-attach a logger when used correctly
  • It can also be configured with a lazy init function to keep code clean.

This reduces the amount of plumbing in many code files.

It will detect if the provided object/service supports these features. So if it's used for anything that doesn't support logging it will just behave like Lazy.
