iLTracer: Changes the way the tracer variables are handled. The options are as follows:

0- Conservative tracer constrained between 0 and the density. The tracer behaves like a density in its advection.

1- Lagrangian tracer constrained between 0 and 1. Instead of behaving like a density the tracer behaves like an incompressible fluid. This is the same tracer that is used by MHD-TVD (a sister code of AstroBEAR developed by Ryu et. al.). See MHD_physflux for more information on the Lagrangian tracer.

2- Lagrangian tracer constrained by be above 0.
