    Branch dev_2022_sette_updates. Add support for running SETTE on detached HEADS. This occurs when older commits are checked out for testing. A detached HEAD is not associated with a branch but these changes will, at least, recover an appropriate date for the commit being tested rather than referring to the current origin.

# SYNOPSIS

#
# ::
#
#  $ ./set_namelist INPUT_NAMELIST VARIABLE VALUE 
#  $ post_test_tidyup 
#
#
# DESCRIPTION
# ===========
#
# function superegrep
#   input variable value
#
# function set_namelist
#   input namelist_name variable value
#   output namelist
#
# function post_test_tidyup
#   creates nemo_validation tree, and save output & debug files
#   this function creates tree of validation in NEMO_VALIDATION_DIR as follows : 
#
# NEMO_VALIDATION_DIR/WCONFIG_NAME/WCOMPILER_NAME/REVISION_NUMBER(or DATE)/TEST_NAME
# 
# NEMO_VALIDATION_DIR           : is choosen in param.cfg
#
# WCONFIG_NAME                  : set by makenemo at the moment of compilation
#
# WCOMPILER_NAME                : set by makenemo at the moment of compilation
#
# REVISION_NUMBER(or DATE)      : revision number by svn info, if problems with svn date is taken
#
# TEST_NAME                     : set in sette.sh for each configuration to be tested (directory TEST_NAME is created under ${NEW_CONF} directory )
