Add a database schema that stores (non-)learnable relations of meaning between words

[ISibboI]

The schema should map between two words of arbitrary language.
It either encodes that two words share a meaning, or that they do not.

In the sharing case, if they are of the same language, they encode synonyms.
If they are of different languages, they encode a standard mapping of meaning between the language.

In the non-sharing case, the entry means a false friend relation. This can be used to discover common errors of language learners and to train against them.

In any case, there is an array of explanations about contexts in which this meaning is valid, or explanation of the false friend.

• Figure out if this should be stored in two separate tables or in one
• Design the schema
• Implement the schema
• Document the schema
