Minor change, increase adam-cli usage width to 150 characters

Most of my terminal windows are set wider than 60 characters, merge or close without as you wish.

The Args4J documentation isn't great (http://args4j.kohsuke.org/args4j/apidocs/org/kohsuke/args4j/CmdLineParser.html#setUsageWidth(int)) -- does this only affect the usage of the output for errors, or is it changing anything about the input at all?

All automated tests passed.

Thanks for the quick feedback. For all I know it just helps with line wrapping when generating --help option documentation, e.g. this lovely one from README.md

 -spark_master VAL                      : Spark Master (default = "local[#cores]
                                          ")

Eeesh. That is ugly. More searching on teh web seems to confirm my suspicions about it being for line wrapping in error/info reporting? So I'll let it sit for a few minutes, and then merge if there are no objections.
