cursor lag #118
Description
[Non-preferred enhancement]
Add an option to have the cursor position be based on the mouse position from 0 - 1000 ms ago (or the sample closest to that). Off by default. Should work with all other features and the settings should stored in the JSON. The cursor delay in ms should be stored in the data (so there will be a new column in both the trial-wise csv files, and the complete data files) but not interfere with data processing.
