/// Abstraction for Tui's actions

/// Contains 4 actions :
/// - EncryptObject
/// - LaunchParams
/// - ShowHelp
/// - Browse
///
/// Only implements the `execute(&self)` method, that `matches` the *action* and calls the corresponding function, and the `from_str(&str)` method, that maps an &str to an EnkryptitTuiAction (and returns `None` if the &str does not correspond to any action.)
///
/// The `Exit` action is directly handled by the `launch_ui()` function itself.
///
/// In fact, the content of the enum isn't used here. It is only used in `/tests/`. That's why we need to keep it.
