/// Macro that *"hides"* the string literal in the binary at compile time.
///
/// This procedural macro accept **only string literals** that starts and ends with `"`.
///
/// Panics only when the first token tree is not a string literal, any followings are ignored. <br>
/// Returns a `String` collected from a vector of chars.
///
///
/// ## Expansion
/// ```rust
/// hoax!("cat\n")
/// ```
/// is the same as
/// ```rust
/// {vec!['c', 'a', 't', '\n',].iter().collect::<String>()}
/// ```
///
/// ## Example
/// ```rust
/// #[macro_use] extern crate hoax;
///
/// println!("{}", "I am not hidden :c");
/// println!("{}", hoax!("I guess I am hidden c:"));
/// ```
///
///
