%
%SST2WFA: Convert events from SST form to WFA form.
%      WFA - WaveForm Array form, events separated in nx1 waveform array
%          - (or) into 1xl cell array, each cell containing a nx1 waveform 
%          - array of events from a separate station/channel.
%      NAN - NaN form, (1xl waveform) for l station/channels with events in 
%            one time series w/ non-events = NaN. 
%      SST - Start/Stop Times form, nx2 array of matlab start/stop times
%            (or) 1xl cell array, each cell containing nx2 start/stop
%            times from a separate station/channel.
%
%USAGE: wfa = sst2wfa(sst)
%
%INPUTS: w    - Waveform object that contains events
%        sst  - Events (WFA form)   
%
%OUTPUTS: wfa - Events (WFA form)
