GEOMESA-159 Eliminate redundant copies of a value in the SimpleFeatureFilteringIterator
GEOMESA-288 Export to stdOut

Exporting to stdOut is now achievable by giving the export command the -s or --stdout flag. Additionally, the list and describe commands now have a -q or --quiet option for better piping of their outputs.

the help for the command line tools a bit.
GEOMESA-302 Export overwrites files without prompting

Exported files are now guaranteed to have a unique filename through using File.createTempFile,
which appends a unique id to each file name. The current DateTime is also appended
to make it easier to identify exported files.
