It's quite hard to encapsulate something this large. This refactor
contains multiple attacks on the current architecture and is changing
things that were probably created quite a while back then. Luckily this
was done in increments so it mustn't be that impossible to recall what
has been done. I just need to relax my memory a little bit.
So the basic idea was quite simple. Let's distingush metas and normal
indexers a little bit more. Both of them were originating from
BaseIndexer, however very little of the functionality was actually
shared between them. Actually quite a few things made it even harder to
implement a different kind of indexer, especially for a newcomer for
both Jackett and C#.
Then in order to further reduce whatever was encapsulated in
any kind of, a couple things had to be changed. Like CardigannIndexer,
which probably had quite a mindshift change. IndexerManager and the
configuration management were also encapsulated and refactored, and now
I have a feeling that although the code could be improved, at least the
responsibilities of services and what they actually do is now clearer.
Anyhow, it would be safe to assume that I will not be able to go
step-by-step and define everything that has been changed. I'm sorry.
