=== Description

Reorganisation of split-explicit solver, separation of Asselin filter and lateral boundary code from _atf routines and rationalisation of euler timestep code to a single instance. Ideally this work should start from the basic implementation of Do loop macros (KERNEL-02_Coward_DoLoopMacros_part1)

=== Implementation

{{{#!box width=35em help
Describe flow chart of the changes in the code. \\
List the Fortran modules and subroutines to be created/edited/deleted. \\
Detailed list of new variables to be defined (including namelists), \\
give for each the chosen name and description wrt coding rules.
