 The outflow module injects a fraction of accreted mass, momentum and angular momentum back into the grid following each accretion time step and between hydro advances.

 Before we discuss the details of this routine, let us briefly recall the accretion prescription here. The feedback module is currently configured to work with the Bondi accretion routine in the code (aka Krumholz accretion). This routine establishes a mass cut-off of gravitationally unstable material around the sink particle (in a control volume of radius = 4dx). Any mass greater than this cut off is removed from the ith cell in this volume (i.e. ''is accreted'') and placed into the sink particle. The ''total'' accreted mass is then given by:

 Gets mass and momentum injection exact, but then guesses at angular momentum injection. At this step it can then mess up the linear momentum injection, which causes an iteration for the L again. This happens back and forth until some small error is achieved. Question -- under what circumstance does this fail? Something about discretization error in the routine, because the kernel is only 4 zones across?
