5786b7f457 EVOLUTION: Move tm and dtm calculation befor applying source terms. 
If we have time dependent source terms, we should pass tm and dtm to
subroutine update_sources().

769e69d704 EVOLUTION: Initialize array du in update_increment(). 
We do not update all elements of array du(:,:,:,:) in
update_increment(), therefore some of its elements may be NaNs. Make
sure that all elements have arithmetic representation by initializing
du(:,:,:,:) with zeros.

Also, indicate that array du(:,:,:,:) is only output argument.

81bec38a77 EVOLUTION: Move here update_increment() from SCHEMES. 
Subroutine update_increment() was using time information which broke the
source term contribution. It has been moved to module EVOLUTION and its
arguments have been simplified.

The time step is now directly taken into account in the time integration
subroutines.

f874511673 EVOLUTION: Update primitive variables before boundaries. 
The new order is to first, convert the updated conserved variables to
their primitive representation in the block interiors, update boundaries
of the primitive variables, and finally, convert the primitive variables
at the ghost cells to conserved ones.

The change updates the primitive variables in the block interiors before
the boundary update.

1ed3747efb EVOLUTION: Turn on the selective update for refined blocks. 
Now, the selective update after refinement/derefinement process is on.
Before checking the refinement and update the mesh, We set all blocks to
not be updated. Then, only blocks which are refined or derefined
including all their neighbors, are set to be updated. This reduces the
repeated work, i.e. boundary update and variable conversion, on blocks
which didn't actually change.

After the mesh refinement, boundary and variable update, we mark all
blocks to be updated, so the regular temporal integration process works.
