# cli_getThemeName.sh -- This function manipulates the current
# absolute path to extract the theme name from it. If there is no
# theme in the path, this function returns an empty string.
#
# Theme names are stored in directories immediatly under
# Themes/Motifs/ directory and and can be named using letters and
# numbers. When rendering themes under branches/ directory structure,
# theme names are also built using the branch numeration the theme is
# being rendered for.
#
# Branch enumeration start at number one and increment one unit each
# time a new branch is created from the same trunk development line.
# If a branch is created from another brach then a new directory is
# created inside the source branch, using the same enumeration schema.
# So, we may end up with paths like
# branches/.../Themes/Motifs/Flame/1,
# branches/.../Themes/Motifs/Flame/1/1,
# branches/.../Themes/Motifs/Flame/1/2,
# branches/.../Themes/Motifs/Flame/2,
# branches/.../Themes/Motifs/Flame/2/1, and so on.  In all previous
# examples the theme name holds the branch enumeration schema too.
