Please consider converting from space indentation to tabs to improve code for persons with visual impairments

# Convert to tabs to improve code for persons with visual impairments

I like to reference the [Code of Conduct](https://dotnetfoundation.org/code-of-conduct), and point out that the current code base, due its usage of spaces for indentation, is problematic for persons with visual impairments.

See also this [article regarding the problems of spaces as indentation for developers with visual impairments](https://www.reddit.com/r/javascript/comments/c8drjo/nobody_talks_about_the_real_reason_to_use_tabs/).

I like to start a discussion about improving the accessibility of the code for people with disabilities, by changing the coding styleguide to change the indentation to tabs, and also converting all indentation in the code.
