This crate provides high-level access to the applet API.

In particular, it provides the following:

• A panic handler that prints the panic info and traps.
• A global allocator using the rlsf crate.
• High-level wrappers around the applet API.

The high-level wrappers provide the following:

• A safe API. (The applet API requires unsafe.)
• Rust types like byte slices (instead of their internal representation).
• Closures for callbacks.
