Basic Idea:
Given two graphs g and f, 1*g + 0*f show g; 0*g + 1*f shows f.
Have a variable 0 < t < 1, (1-t)*g + t*f gives a linear transformation between g and f. g fades out while f fades in.
It works just like interpolation methods.

f0 = smooth transition from 0 to 1
f1 = repeat of f0 and faster
Problemf0 & f1 never touches 0 and 1. They only approach it.
f_adeIn makes sure f(0) touches 0 and f(1) touches 1.
