Default setting for variables

[Shikhar-Srivastava-16]

rustsat's native variable management generates solutions to decision variables in a Ternary format:

pub enum TernaryVal {
    True = 0,
    False = 1,
    DontCare = 2,
}

The conversion to binary supports default settings for variables which do not affect the satisfiablility of the expression given to it.
At the moment, I have this set to false as a placeholder.

There are a few ways this can be dealt with, including but perhaps not limited to:

1. Treat this as a set default value - either false or true
2. Treat this as a command line flag which allows us to set this value at runtime
3. Just treat the solutions as Ternary, not Binary

I am unsure of how I can do this and I would like some advice.
Thanks

• Treat this as a set default value - either false or true

This will change the number of solutions, which may break integration testing against Conjure.
