There show be a short description near the menu explaining the steps, ie, right click to add a new fiducial, left click to move it, delete to remove. Also a short description of what the user is supposed to select might be helpful, ie, 'select window for QRS complex'.

In the header info stage, the files should be read one at a time, and only the header, instead of loading in all the data at once just to get the data.

there could be a label near the settings window to indicate that it is where the data is chosen. That way if the settings window is closed or not opened somehow, the user still knows where to start.

Documentation needs to be cleaned up and and update

OS: Windows 10
Matlab Version: R2018a

The Auto fiducilization does not work as expected on Windows 10 under certain circumstances as follows:
The data file contains four leads. Two leads. The leads are split into two groups of two. When autofiducilizing using either all four leads (both groups) or just one group only the first group is shown in the user interaction window for autofiducilization. On Mac OS Matlab R2016b all four electrodes are shown in the user interaction autifiducilization screen.

There is a lot of code, especially in allUtilFunctions, that doesn't seem relavant to the newest version. We need to sort through it and remove unnecessary parts of the code
