factor string to function, always print digit count
extract semi-customized primecheck function
use prime_check again on output of filtering
save factorbase (including new numbers) on exit, general cleanup
add ECM runs to find new factors, feature complete!
refactor ecm limit launching, simpler params hash
updated factorbase from yesterday's run
change ecm limits and counts to match ecmnet "recommendations"
shuffle work so we can make progress on small factors without waiting for all larger factors between runs
paramaterize smaller ecm limits, don't push work back if we didn't make progress during ecm
more interesting limits for factoring
more factoring progress
