[Eeglablist] Extracting Phase Angle from ITC Matrix

[Scott Makeig]

Note that when you turn on the newtimef option that gives you a 'striped'
ITC, the function simply multiplies the [0,1] ITC magnitude value by the
sign (+/-1) of the ITC angle -- sign(angle(itc)) -- thus giving a fairly
good graphic view of the portion of the ERP accounted for by the ITC at each
frequency when probability masking is also turned on.
