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::*;
// Simple group of components that consists of multiple fields
struct TestGroup { pub base : StepperCtrl, pub arm : StepperCtrl }
fn main() { let test = TestGroup { base: StepperCtrl::newsim(StepperConst::GEN), arm: StepperCtrl::newsim(StepperConst::GEN) };
let test_ref : &dyn SyncCompGroup<2> = &test;
// Usually requires multiple curve builders
let path_builder : PathBuilder<2> = test.create_path_builder();
} ```
