Add field delimeter to error message when segment has less fields than required

[andrewshawcare]

First off, thank you so much for this tool and the wonderful exception messages you provide in this tool!

They are so good, in fact, that I was almost able to construct an EDI mapping from just the exception messages alone (they do a wonderful job of hinting at what to do next).

To that end, it would be great if, when the number of fields is less than there should be for a segment, to add information about what the current field delimiter is. That way, the user can add the required amount of field delimiters to move on to a successful parse or, in the worst case, the next error message they can use to continue.

This idea would be great to add for any location in parsing where a delimiter is required.

Here's the exception in question:

smooks-edi-cartridge/edi-sax/src/main/java/org/smooks/edi/edisax/EDIParser.java

Line 725 in dc705c2

throw new EDIParseException(edifactModel.getEdimap(), "Segment [" + segment.getSegcode() + "] expected to contain " + (numFieldsExpected - 1) + " fields. Actually contains " + (currentSegmentFields.length - 1) + " fields (not including segment code). Currently at segment number " + segmentReader.getCurrentSegmentNumber() + ".", segment, segmentReader.getCurrentSegmentNumber(), segmentReader.getCurrentSegmentFields());

Again, thank you! :)
