/**
 * An improved and more pleasant base Email class to use on your project
 *
 * This class is fully decoupled from the EmailTemplate class and keep be used
 * independantly
 *
 * Improvements are:
 *
 * - URL safe rewriting
 * - Configurable base template (base system use Email class with setHTMLTemplate to provide content)
 * - Send email according to member locale
 * - Check for subject
 * - Send to member or admin
 * - Persist emails
 * - Parse body (multi part body is supported)
 * - Plaintext takes template into account
 * - Disable emails
 * - Unified send methods that support hooks
