    2 1.  Want to find steady state solution interior to super-critical point

     21.  Want to find steady state solution interior of super-critical boundary point
    332.  Problem is that none exist with adiabatic EOS
    443.  Would like interior solution to be steady state and inflowing
    … …  
    665.  And the density can also be arbitrary.
    776.  This interface can therefore generate three waves (with a shock/rarefaction, contact, and shock/rarefaction)
    8 7.  We would like there to be no inward waves - so only a right moving shock.
    9 8.  The mach number of this outward moving shock - is the only 'free' parameter.
    10 9.  There is a lower limit for the mach number so that the inward solution is critical (or subcritical).
    11 10.  And there is an upper limit for the mach number if we require the flow to remain inward.

     11=== Single Shock ===
     121.  For shocks, the mach number is the only 'free' parameter.
     131.  There is a lower limit for the mach number so that the inward solution is critical (or subcritical).
     141.  And there is an upper limit for the mach number if we require the flow to remain inward.
     151.  As the shocks move, the post shock values do not fill in the bondi curve - nor do they satisfy the jump conditions for a single shock.  Instead a rarefaction forms
