/**
 * Helper class for anonymization of data
 *
 * This functions includes a collection of methods that are invoked
 * from the backup process when anonymization services have been
 * requested.
 *
 * The name of each method must be "process_parentname_name", as defined
 * byt the @anonymizer_final_element final element class, where
 * parentname is the name ob the parent tag and name the name of the tag
 * contents to be anonymized (i.e. process_user_username) with one param
 * being the value to anonymize.
 *
 * Note: current implementation of anonymization is pretty simple, just some
 * sequential values are used. If we want more elaborated generation, it
 * can be replaced later (using generators or wathever). Don't forget we must
 * ensure some fields (username, idnumber, email) are unique always.
 *
 * TODO: Improve to use more advanced anonymization
 *
 * TODO: Finish phpdocs
