% [x, y] = SoundTableSection(obj, action, [arg1], [arg2])

% This plugin makes a Sound Table window that manages any number of f1/f2
% stimulus sounds.  The sounds specified in this table are sent to
% SoundManagerSection as 'Soundx', where 'x' is the row where this sound
% appears in the table.
% -----------
% obj      Default object argument.
% action   One of:
%   'init'     Initializes the plugin. Sets up internal variables
%               and the GUI window.
%   'n_stimulus_cycle'      if a value <1 is entered for n_stimulus_cycle,
%               reset it to 1.
%   'StimTimeStart'         disables/enables FromAnswerPoke and
%               n_stimulus_cycles as appropriate
%   'display_table'         formats the sounds stored in stims to be
%               displayed in the table
%   'sttable'               when a row is clicked in the table, copy the
%               values in that row into the NumeditParams for the
%               corresonding fields.  This makes it easier to modify the
%               sounds and then update them.
%   'side'                  enforces the value entered in side to be either
%               'r' or 'l'.
%   'pprob'                 enforces the value entered in pprob to be [0 1].
%   'set'                   a useful action that takes 3 extra arguments:
%               the sound pair to be modified, the field to be modified,
%               and the new value.  For example, if we want to set the
%               f1_dur of sound pair 4 to 0.7:
%                 SoundTableSection(obj, 'set', 4, 'f1_dur', 0.7);
%   'get'                   a complementary action to set that takes 1-2
%               extra arguments.  To get the number of sounds currently
%               defined or a matrix of all sides, use 'nstims' and
%               'all_sides'.  To get a field from a specific sound pair,
%               for example, the pprob of sound 2:
%                 SoundTableSection(obj, 'get', 2, 'pprob');
%   'add_pair'              adds a new row to the table using the values 
%               currently in the editparams.  Makes the appropriate row in
%               stims and constructs the sound.
%   'delete_pair'           deletes the row currently selected in the table.
%   'update_pair'           replaces the row currently selected in the
%               table with the values entered in the editparams.
%   'next_trial_sound'      returns the row of one pair chosen randomly
%               according to the pprobs.  Passing an extra variable 'l' or
%               'r' forces a sound for that side to be picked.
%   'make_sounds'           constructs all sounds specified in stims and
%               sends them to SoundManagerSection.  Sounds are named
%               'Soundx', where x is the row this sound pair appears in the
%               table.  If passed an additional optional parameter, then
%               only this particular row is rebuilt and set in SoundManagerSection.
%   'check_norm'            checks that a valid set of sounds have been
%               specified, and if not, print a error message at the field
%               at the right bottom corner of the window.  Criterion for
%               all systems go: 1) pprobs sum to 1, and 2) at least one
%               left and one right sound are defined.  If these are both
%               met, go_flg is set to 1 and the message box turns green;
%               otherwise, go_flg is 0 and the message box turns red.
%   'get_go_flg'            returns the value of go_flg.
%   'normalize'             normalizes pprobs so they sum to 1.
%   'play_sound'            plays the currently selected sound in the table.
%   'stop_sound'            stops the currently selected sound in the table.
%   'get_n_sound_pairs'     returns the number of rows in stims.  This can
%               also be accomplished with the 'get' action.
