Added extra error trap to Moses' train-model.perl processing to terminate processing when open source MGIZA++ fails to report the error.
Refined error handling logic where a secondary error masked the original fatal error.
New vocabulary logs under the BUILDS\lm and BUILDS\tm subfolders. Previous vocabulary files were a simple list of vocabulary. The new format is a tab-delimited file with vocabulary in the left column and the count in the right column.
