/**
* @class Email
* Mit dieser Klasse kann ein Email-Objekt erstellt
* und anschliessend verschickt werden.
*
* Das Objekt wird erzeugt durch Aufruf des Konstruktors:
* Email()
*
* Nun wird der Absender gesetzt:
* setSender($address, $name = '')
* Parameters: $address - Die Emailadresse
* $name - Der Name des Absenders (optional)
*
* Nun koennen in beliebiger Reihenfolge und Anzahl Adressaten (To,Cc,Bcc)
* der Mail hinzugefuegt werden:
* (optional und mehrfach aufrufbar, es muss jedoch mindestens
* ein Empfaenger mittels einer der drei Funktionen gesetzt werden)
*
* addRecipient($address, $name = '')
* addCopy($address, $name = '')
* addBlindCopy($address, $name = '')
* Parameters: $address - Die Emailadresse
* $name - Der Name des Absenders (optional)
*
* Nun noch ein Subject setzen (optional):
* setSubject($subject)
* Parameters: $subject - Der Text des Betreffs
*
* Der Email einen Text geben:
* function setText($text. )
* Parameters: $text - Der Text der Mail
*
* Bei Bedarf kann man sich eine Kopie der Mail zuschicken lassen (optional):
* setCopyToSenderFlag()
*
* Sollen in der Kopie zusaetzlich noch alle Empfaenger aufgelistet werden,
* muss folgende Funktion auch noch aufgerufen werden (optional):
* function setListRecipientsFlag()
*
* Methode gibt die maximale Groesse der Anhaenge zurueck
* size_unit : 'b' = byte; 'kb' = kilobyte; 'mb' = megabyte
* getMaxAttachementSize($size_unit = 'kb')
*
* Soll die Nachricht als HTML Code interpretiert und versendet werden,
* muss folgende Funktion auch noch aufgerufen werden (optional):
* function sendDataAsHtml()
*
* Am Ende muss die Mail natuerlich noch gesendet werden:
* function sendEmail();
