Minifrac Nolte ACA Linear Time

There are two Minifrac Nolte After-Closure Analysis (ACA) linear time functions. F_L1 is an approximation of F_L2 and the two time functions converge quickly.

Note:

Both time functions are bounded by 1.0 (at early shut-in time) signifying the time of closure, and 0.0 (at late time) representing an infinite shut-in time.
