/**
 * The Favor class is an extension of the Database handler
 *
 * represents a favor, the basis of our app, which users can then react with
 *
 * A favor has a:
 * title & an owner
 * a description, location and deadline
 * optionally it is also possible to upload a picture (which is saved as reference in the favor)
 *
 * as helpers we store the creation date and the owner email
 *
 * and most importantly: how many token is it worth and for how many people is the favor accessible
 * and last but not least a list of people which are interested
 *
 * A favor is a favor and should have a database entry (since it is not literally one)
