/*
SEQUENCE GROUPING MANAGEMENT MODULE
allows to define a template of layers, then create groups of keys using that template
groups are composed of one key per layer and a cue
cue is used to define the time position of the keys
values of each key can be changed
keys are grouped by name, and groups can be saved/loaded to a file
