Adding a precessing, bipolar, 2-component outflow to the sink particle routine, following ​Federrath, et al. 2014

Density injection

-Define a spherical cone centered on the sink particle of height rsink
-Prescribe some function that distributes accreted mass over the cone, with some radial and angular dependance
-Given this is a discretized operation, and the sink is not necessarily positioned at the center of the conical region, the masses in the 2 lobes may be slightly different
-Thus, compute a correction factor for each of the cells to multiply the mass by when applying it to the cones
-Rinse and repeat
