/*The logic outline is this ....

Make an array of the format of the ORDER message from the table EDI_ORDERS_Segs

Get the list of files in EDI_Incoming_Orders - work through each one as follows

Read in the flat file one line at a time

Compare the SegTag in the flat file with the expected SegTag from EDI_ORDERS_Segs

parse the data in the line of text from the flat file to enable the order to be created

Create a html email to the customer service person based on the location
of the customer doing the ordering and where it would be best to pick the order from

Read the next line of the flat file ...

If the order processed ok then move the file to processed and go on to next file.
