Add: Most basic context changing feature.
Update: setContext() now has relative priority feature.
Add: The basic change context by pattern response group feature.

Update: Also, now when generating the knowledge base we loop by reference.
This mean we no longer need the index variable.
Add: Just a few notes to myself.
Merge branch 'feat/context'

Most of the work on the context changing topic is done.
Therefore I am merging the branch.
