/**
* The base class for {@link module:core/context~Context} plugin classes.
*
* A context plugin can either be initialized for an {@link module:core/editor/editor~Editor editor} or for
* a {@link module:core/context~Context context}. In other words, it can either
* work within one editor instance or with one or more editor instances that use a single context.
* It is the context plugin's role to implement handling for both modes.
*
* There are a few rules for interaction between the editor plugins and context plugins:
*
* * A context plugin can require another context plugin.
* * An {@link module:core/plugin~Plugin editor plugin} can require a context plugin.
* * A context plugin MUST NOT require an {@link module:core/plugin~Plugin editor plugin}.
