/* General Logic
/ Read the input stimulus. Generate a blanked out stimulus that corresponds
/ to the original verse. Display the whole strophe in a self-paced manner.
/ Before displaying the next word, check whether a probe task needs to be
/ inserted (based on whether the word to present would trigger a probe task).
/ If so, present the probe task. In the case, once the probe is over,
/ if the verse is still not over, continue presenting the verse until it is over.
/
/ Conventions expected in the input file
/ Text phrases to be presented together: joined by _; Eg., Die_Strophe.
/ Next line indicator: ' +' (A space followed by a plus sign).
