   Constants Have Const Pragma

Description
===========

.. start_description

Constants have the const pragma set.

.. end_description

Rationale
=========
This enforces compliance with a specific modeling standard by ensuring that constants make use of the ``const`` pragma.
This means that, in the generated C code, constants are declared as ``const`` instead of ``#define`` macros.

One possible use case is to ensure style homogeneity of the KCG-generated C code with external code with which it is meant to be integrated.

Verification
============
This rule checks that all scalar constants have the ``C:const`` pragma defined.

Resolution
==========
Add the "Const" KCG pragma onto the offending constant.

Customization
=============
N/A.
