Num enum

[perlindgren]

Enum based implementation for handling parameters.

Advantages:

• improved readability, the connection between parameter numbers and their purpose becomes clean.
• improved robustness, less risk of introducing bugs,
  • stable parameter indexing, with possibility to grouping
  • parameter index uniqueness guaranteed at compile time
• improved ergonomics, less code repetition, traits are derived that implements most of the "propagation"

Disadvantages:

• a few dependencies introduced, (num-enum and strum), requires the user to understand how they are used for declaring parameters.
