//! This crate provides a a self-owned data structure with an internal heap and garbage collection.
//!
//! NData supports objects, arrays, strings, integers, floats, 
//! booleans, byte buffers, and null. DataObject, DataArray, and DataBytes instances 
//! maintain reference counts. Garbage collection is performed manually by calling the 
//! type's gc() function.
