A function useful to merge layers
This function can be used in scripts written in the PythonLanguage to merge layers.

The layers of an image can be grouped using a convention in their names. The groups with the same prefix belong to the same group. The prefix is the part of the name before the character '-' (by default).
To use another delimiter character, change the variable 'delimiter'.
The layers with a name starting with a '#' are not considered.
For example, you can have a stack of layers that looks like:
boy-colour
boy-ink
dog-text
dog-colour
dog-ink
#Background
The groups here are:
boy
dog
