Seed rule set added

Function seedUpdate() will use the new rule set only if the boolean
useSeed is true.
Seed rule choice added to JMenu

You can now select the seed rule set from the JMenu.  This is done by
cellAndGridSquare using the function setSeedRule() to set the choice to
true

if getSeedRuleStatus() is false then the normal update function is
called.  If it is true then the seed rule set update function is called.
