ImGUI runtime inspector

igri is a runtime inspector powered by imgui-rs

use igri::Inspect;

#[derive(Inspect)]
pub struct MyCoolStruct<T> {
     xs: Vec<T>,
}

dummy feature

We want to disable developer UI on release build. Enable dummy feature flag to turn off #[derive(Inspect)] expansion.

Be sure to out put other calls to igri, too!
