Cargo Features

Ckmeans has no features set by default.

[dependencies]
ckmeans = { version = "1.0.6", features = ["headers"] }
headers = cbindgen

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
