EDI-INVOIC

[rdoppeltplus]

Hi, thanks for your awesome work. Would it be possible to add an INVOIC sample in the samples? I just want to make sure to use everything correctly and get the correct EDI Message... I'm not really sure if I use the library the right way, 'cause there's always an Error in my created Messages when they get too much information (like if I pass too much information for the Invoic).
