 This script is a stand-alone function that can be useful as a sandbox to develop the PTB audio/visual stimulation of your experiment. No input/output required.
 
-Here, a tutorial from https://peterscarfe.com/contrastgratingdemo.html is provided for illustrative purpose (notice that some vars' name are updated to our code style). For your use, you will delete that part.

 It is composed of two parts:
  - a fixed structure that will initialize and close PTB in 'debug mode'
     (`PsychDebugWindowConfiguration`, `SkipSyncTests`)
- - the actual sandbox where to set your dynamic vars (the stimualtion
+ - the actual sandbox where to set your dynamic variables (the stimulation
    parameters) and the 'playground' where to develop the stimulation code
 
- When you are happy with it, ideally you will move the vars in `setParameters.m` and the stimulation code in a separate function in `my-experiment-folder/subfun`. The code style and vars name is the same used in `cpp-lln-lab/CPP_PTB` github repo, therefore it should be easy to move everything in your experiment scripts (see the template that is annexed in `cpp-lln-lab/CPP_PTB`).
