Text progress bar (CLI & GUI)

Generates a progressbar for display in the MATLAB command window or CLI

This function generates a textual bar which visualizes the progress of a task. Consecutive progress bars overwrite the previous instance instead of outputting on a new line, making updates seamless.
The number of segments as well as the characters which make up the progress bar (delimiters, completed, ...) are fully customizable.
Works for both GUI and CLI instances of MATLAB.
