declare a const array
Modest currently does not allow an array with a `const` / readonly modifier:
`> error: Constants cannot be of composite type.`
Background:
I have a model with very large `int`-arrays containing only constants needed for computation. Because I cannot declare them as `const`:
- `mcsta` writes them in every state of the scheduler gererated with the new `--scheduler` flag,
- `modes` writes them in my traces,
- `mosta` shows them in the global variables section (practically rendering the output useless because `dot` cannot handle this).
