/**
*  2 methods below, 1st one entire, 2nd one skeleton
*  yes, for generate, could/might set the x/y variables outside of method
*
*  My goal, which I can't figure out how to do is to PASS the value of
*  variable "rangeX" created in generate()  to be the value of "length"
*  for method 2
*  have messed around for quite awhile, not getting anywhere, still newbie
*  understand scope of variables is somehow hindering this process but not 
*  sure what to do.
*  
*  Thank you!
