Version of TrialTypeOutcomePlot that handles having trial types and outcomes built on the fly starting from an empty array (and not just via a pre-allocated array of NaNs as I had done previously which is clumsy and restrictive).

The changes are transparent unless you:

1. build trial type and outcome lists by accretion such that the length of each list is equal to the currentTrial.

   Usage example:

    % trial type chosen on the fly based upon current Protocol Settings
    TrialType = pickRandomTrials_blocks(S.Block.Table); 
    % update outcome plot to show trial type of current trial with outcome as yet undefined (NaN)
            TrialTypeOutcomePlot(BpodSystem.GUIHandles.OutcomePlot, 'update', ... 
                currentTrial, [BpodSystem.Data.TrialTypes TrialType], [BpodSystem.Data.TrialOutcome NaN]);  

2. initialize Trial Types as NaNs and call 'init' prior to supplying the first trial type.
