[Eeglablist] renaming specific occurrence of events

[Scott Makeig]

Brian -

Rather than using additional event type codes for all these variants,
EEGLAB allows use of user-defined event *fields* in the EEG.event
structure. you might title the new field 'PresentNumber'  (or whatever). I
am sure getepoch() allows searching on event fields other than type... In
our parallel HED (Hierarchical Event Descriptor) system building effort, we
also use fields in the 2-D ASCII 'events.tsv' event table, in combination
with HED string declarations in an accompanying events.json file, to more
completely describe the natures of the events recorded in a neuroimaging
experiment ('What does event type 1008 mean here?!'].   HED can simplify
analysis, and is important for cross-study analysis including machine
learning, applied to data from any variety of sources including shared data
archives such as our NEMAR.org.
