[Eeglablist] changing event types

[Scott Makeig]

Jeff -

Else - or in addition - please consider annotating events using HED
(Hierarchical Event Descriptors) - see hedtags.org.  EEGLAB has functions
to flexibly search for events by tag, and will be adding functions using
HED tags to ready data for machine learning - within or across datasets.
HED is officially accepted within all the BIDS modality formatting
standards and is in fact the only standard for describing events in detail
using a common vocabulary and syntax.
