Turn TOJ.m into a proper experiment program, with the following characteristics:

 20% chance of SOA = 4
 20% chance of SOA = 2
 30% chance of SOA = 1
 30% chance of SOA = 0
 For each SOA condition, there must be an equal number of first_left, first_right dot conditions. The experiment should have at least 5 trials per SOA x Dot_First condition. The data should be saved in one file, with the following information:
 Subject number, Trial number, SOA condition, Dot_First condition, response, confidence.
 A header at the top of the file with the name of each column should be included.
 Challenge Problem: Add a condition where a brief cue is presented 50 ms prior to the first dot, with no location validity.
 Challenge Problem: Observers use the mouse and click on the relevant box. And record that response and highlight the box.
