Zero-dimensional diffusion problem which can be tested against
exact solution.
=================================================================
Unsteady dispersal problem:
dF/dt=exp(t)-5F
Initial conditions:
t=0, F=1
Exact solution:
F=1./6.(exp(t)+5.exp(-5t))
==================================================================
One computational cell is used in this study of the
time variation of pollutant concentration.
