testnagg.sh
    Changed multipls SVM products tests to -g no since GMODO file is removed.
    Added SATMS,TATMS packaging tests.
    Removed extra input and geo granules test which needed GMODO file.  Should be replaced 
    by test with other multi-product files.
nagg_write_granules.c
    Fixed bug in end_write() exposed by multi-product test with -g no.
    Uncommented check for expected granules written in end_write().  It no longer
    fails incorrectly with multiple products.
    Added code to write Ending_Date attribute to fill granule datasets
    This also corrects the AggreagateEndingDate attribue for aggregate datasets.

Tested jam & koala, gcc & icc.
