	help:"meld accepts two inputs only - 0 and 1\nmeld returns either 0 or 1\nYou must init() before you can use meld\n\nThe process is\n1)Add current input to memory with setmem(input)\n2)Remeber current input with add(input)\n3)Predict next input with prediction=predict()\n\nYou can alter melds behavior by changing the mem/mems length\nor by adding noise to the predict() routine."
