Create Mood Model

Describe your problem

There is no schema yet that defines the Moods.

Describe the solution you'd like

Create a Mood model in the back end which has certain keywords associated with them, as well as emojis. For instance, the Mood "Sad" can have keywords such as "upsetting, demoralizing, insulting", etc.

Additional context

Also ensure that once this Model has been created, all the Post APIs have "Mood" as a field. That is, when composing a post, it should be possible for the user to set a certain Mood as well.
