For the L system, the strings nextgen and prevgen are computed for every
generation until the final generation is reached. For very high values of
gen(number of generations), it takes significant time to compute the
nextgen.
But as given in the reference, higher generations say beyond 10 repeats the
sequence. I think I should set the maximum limit of gen to a more practical
value of around 10 to 20.
