qinit default routines

Below are links to the default `qinit` library routines for Classic and AMRClaw.  

These should never be used

the initial conditions as desired.

qinit routine in GeoClaw

In GeoClaw, there is a library routine that 
sets the surface elevation to sea level by default, and also has the option
of adding a perturbation as specified in the setrun file, see
:ref:`setrun_qinit`.
