spacing fix for comment
infinite ldt catch
changing the way levels are handled
Some logic for the local time stepping (work not being done yet)
Changing to levels being numbered so that the timestep size is dt*2^{level number}
(as opposed to level number the actual power of two)
Making it so that intra and inter can take a second argument
fixing the rates for lsrk
Some checks
another sanity check on scale rates
adding some inter and intra calls
bug fix in determining the smallest time step
Bug fix in an assert, we don't need to check that max level > 0
bug fix in setting up local time step communicators
Starting to handle the local update. Still need to set up the interpolation and
set up the rates after an update
Bug in determining the actual timestep, was multiplying min dt by number of
levels instead of 2^(number of levels - 1)
Storing number of local steps in an array
enabling a prefix for communication (should really refactor the subdomain comm
at some point)
Using a callback function for the prefix instead of a string
Specifying that the comm_args passed to local time stepper should be of type
bfam_subdomain_comm_args_t
Removing the RK stuff for now, since I don't know how to use it yer
