        --- Class for interfacing with the TargetSMS API.

        More information is available on www.targetsms.nl
	You need to register a (sub)keyword before you can use this API

        Note that these examples are provided on an as-is basis. These are a complement
        to our manual, not a substitute.

        Usage:

        $sms = new TargetSMS ($username, $handle, $notify);

        Where:

        $username   	Your TargetSMS username
        $handle		Your TargetSMS handle, see: www.targetsms.nl/handle
        $notify		E-mail errors to this address (not mandatory)

	--- Need support? techsupport@targetmedia.nl (send as much specifics as possible)

/*
	Display_errors should always be turned off in your php.ini, as you don't want to
	show hackers potential interesting information.
	Also, TargetSMS expects a statuscode, and only that. If not, the system will keep
	trying to call your handler.
	The next line fixes for notices and warnings, but not the fatal errors (edit php.ini for those)
