Subject: [PATCH 1/7] Refactor varargin to arguments blocks
Replaces all instances of `varargin` with modern `arguments` blocks.
This improves code clarity, enables tab-completion for optional
arguments, and provides better input validation.
The following functions/methods were updated:
- did.datastructures.emptystruct
- did.file.fileobj.fprintf
- did.file.readonly_fileobj constructor and fopen
- did.fun.plotinteractivedocgraph
- did.fun.finddocs_missing_dependencies
- did.fun.findalldependencies
- did.binarydoc constructor
- did.implementations.matlabdumbjsondb constructor
- did.implementations.sqlitedb methods
- did.implementations.sqldb constructor
- did.database methods
- did.document constructor and setproperties
- testToolbox
- parfor_test

Subject: [PATCH 2/7] Refactor varargin to arguments blocks
Replaces all instances of `varargin` with modern `arguments` blocks.
This improves code clarity, enables tab-completion for optional
arguments, and provides better input validation.
The following functions/methods were updated:
- did.datastructures.emptystruct
- did.file.fileobj.fprintf
- did.file.readonly_fileobj constructor and fopen
- did.fun.plotinteractivedocgraph
- did.fun.finddocs_missing_dependencies
- did.fun.findalldependencies
- did.binarydoc constructor
- did.implementations.matlabdumbjsondb constructor
- did.implementations.sqlitedb methods
- did.implementations.sqldb constructor
- did.database methods
- did.document constructor and setproperties
- testToolbox
- parfor_test
