Added a simple example to use cron and log output

Previously, the documentation suggested using cron to schedule
finglonger poking  at stuff, but left the enduser to figure out how to
do so.

Now the documentation shows an example of using cron. The example also
redirects output to a logfile, making scheduled tasks more easily
debugable.

EDIT: Included change suggested by Cullen in nibalizer/finglonger#2.
