flc:  -all and -show_data options

-all:
  * main script now executes in outer loop
    * sorted-list of planet-names if -all set
    * single planet in list from @ARGV otherwise
  * no command line argument (other than -all) needed for this option
  * added check sub similar to assert, but doesn't fail, just returns true or false
  * re-wrote assert to use check
  * most assert statements changed to next unless check ... so that execution continues with next item in loop

-show_data
  * diagnostic tool for looking at the actual folded time-series data being written to the xml file
