              Fibonacci class

              The Fibonacci sequence is named after italian mathematician Leonardo of Pisa, known as Fibonacci. His 1202 book "Liber Abaci" introduced the sequence to Western European mathematics, althoutgh the sequence had been described earlier as Virahanka numbers in Indian mathematics. By convention, the sequence begin either with Fo=0 or with F1=1.
