/** Class Address is meant to perform most of the access to the table profile_addresses.
 *
 * profile_addresses describes an Address, which can be related to either a
 * Profile, a Job or a Company:
 * - for a Profile:
 *   - `type` is set to 'home'
 *   - `pid` is set to the related profile pid (in profiles)
 *   - `id` is the id of the address in the list of those related to that profile
 *   - `jobid` is set to 0
 *
 * - for a Company:
 *   - `type` is set to 'hq'
 *   - `pid` is set to 0
 *   - `jobid` is set to the id of the company (in profile_job_enum)
 *   - `id` is set to 0 (only one address per Company)
 *
 * - for a Job:
 *   - `type` is set to 'job'
 *   - `pid` is set to the pid of the Profile of the related Job (in both profiles and profile_job)
 *   - `id` is the id of the job to which we refer (in profile_job)
 *   - `jobid` is set to 0
 *
 * Thus an Address can be linked to a Company, a Profile, or a Job.
