/*
SEQUENCE GROUPING MANAGEMENT MODULE

this module builds a representation of a sequence in values using containers
It allows to create groups of keys, a group being a cue and one key per layer.
In a group, all keys sync their time on cue's time, only value can be modified

The sequence with grouping can then be exported and reloaded.

The module checks periodicaly if timeline sequence structure (cues, layers and keys) and
module values structure are in sync. If out of sync, you may either rebuild values structure 
from sequence or rebuild sequence from values
