     * If the field 'autoAttribute' exists here. Then this attribute is an 'automatically mapped' attribute
     * Auto mapped attribute solve the problem of filling in common information like user information.
     * A common example is: Fname, Lname, Address: houseNum, apt, street.
     * 
     * To do an automatic mapping we need to know:
     * - Which external attribute is being filled in
     *     - That will be: attribute that this data block is found in
     * - Which internal field(s) does this attribute use to get overwritten
     * - How does this attribute get overwritten (custom function)
     * 
     * This can be solved with an common ID. As the API standarizes the attribute, 
     * we know the key/value choices and thus we have a function that relys on that mapping
