Design Reference: Refer to Bukkit & Sponge for API Design

[johnbanq]

The Bukkit API is a well-known and long-existed plugin API that almost dictated plugin development on Java Edition for years,its longevity means that it must have got some abstraction right!
The javadoc of its current successor: https://hub.spigotmc.org/javadocs/spigot/overview-summary.html

The Sponge API is a relatively new(but also has been around for a year or two) plugin API that runs on forge,I will put their docs here too:https://jd.spongepowered.org/7.0.0/
I think we should,even must learn from our "java predecessor" to aid us in designing a lightweight，simple to use API by utilizing the expressiveness of the duck-typed language.
