A helper crate for proc-macros used by the [stepper_lib].
Includes a derive proc-macro to implement SyncCompGroup
for a struct consisting of only fields that include SyncComp
.
```rust use stepper_lib::prelude::*;
struct TestGroup { pub base : StepperCtrl, pub arm1 : StepperCtrl }
fn main() { let test = TestGroup { base: StepperCtrl::newsim(StepperConst::GEN), arm1: StepperCtrl::newsim(StepperConst::GEN) };
let _test_ref : &dyn SyncCompGroup<2> = &test;
} ```
