@desc
Wrapper routine that converts from conserved to primitive variables
at every grid cell centre.
@enddesc
@calls
@calledby
@history
Trimmed and altered from the GR3D routines, original author Mark Miller.
2007?: Bruno excluded the points in the atmosphere and excision region from the computation.
Aug. 2008: Luca added a check on whether a failure at a given point may be disregarded,
because that point will then be restricted from a finer level. This should be completely
safe only if *regridding happens at times when all levels are evolved.*
Feb. 2009: The above procedure proved to be wrong, so Luca implemented another one.
When a failure occurs, it is temporarily ignored, except for storing the location of where
it occured in a mask. At the end, after a Carpet restriction, the mask is checked and if
it still contains failures, the run is aborted with an error message. Only used routines
have been updated to use this procedure.

This routine is used only if the reconstruction is performed on the conserved variables.
It computes the primitive variables on cell boundaries.
Since reconstruction on conservative had not proved to be very successful,
some of the improvements to the C2P routines (e.g. the check about
whether a failure happens in a point that will be restriced anyway)
are not implemented here yet.

This routine is used only if the reconstruction is performed on the conserved variables.
It computes the primitive variables on cell boundaries.
Since reconstruction on conservative had not proved to be very successful,
some of the improvements to the C2P routines (e.g. the check about
whether a failure happens in a point that will be restriced anyway) are not implemented here yet.
