ID	FCNS-4
Title	Do not use scripts. Use functions instead.
Priority	Strongly recommended
Severity level	4
Description	Use functions even if there are no inputs or outputs.
Rationale	The scope of variables in a script is not bounded as one might expect. It is therefore safer to use functions instead. Additionally, scripts are not compatible with Matlab Coder.
Exception	Initialization of a project, or specifically creating base workspace structures that are used in models, without the need for assignin.
