checkSuppressAll
Checks if there are any MATLAB Code Analyzer messages being suppressed throughout the file. Code Analyzer messages should generally be prevented. If they are not prevented, they should be suppressed and have an accompanying comment stating the reason for suppression (not checked by checkSuppressAll). It is advisable not to do this throughout an entire file because the same warning may be helpful elsewhere.
