A typical reactive call to persist data in StorIO looks like this:

StorIOSQLite storIOSQLite = ...;
storIOSQLite
        .put()
        .objects(entitiesToPersist)
        .prepare()
        .asRxSingle()
        .subscribe();

However, before we can start using this, we need to figure out a few things:

• How to map SQL data to domain classes and vice versa?
• How to acquire StorIOSQLite interface?

Let's start with the data mapping, which will be later plugged in to the StorIOSQLite interface.
