safestruct gem - Safe Data Structures (Array, Hash, Struct) - Say Goodbye to Null / Nil (and the Billion Dollar Mistake)

Hello,

  I've put together a new safestruct gem / library [1] that collects
  safe data structures (array, hash, struct)
  and lets you say goodbye to null / nil (and maybe)
  to fix the billion dollar mistake.

  How can the code work without nil?

  Let's say hello to zero :-).
  The new rule for NO null/nil ever (again) is:

  **All variables - including structs, arrays and mappings (hash
dictionaries) -
  MUST ALWAYS get set (initialized) to ZERO (default) values.**

  What's zero?

  |----------------|----------------------------|
  | Type           | Value                      |
  |----------------|----------------------------|
  | Integer        | `0`      or `Integer.zero` |
  | Bool           | `false`  or `Bool.zero`    |
  | String         | `''` or `String.zero`      |
  | Array          | `[]` or `Array.zero`       |
  | Mapping (Hash) | `{}` or `Mapping.zero`     |
  | Vote (Struct)  | `Vote.new( 0, false, 0, '0x0000')` or `Vote.zero`  |
  | Address        | `0x0000` or `Address.zero` or `Address(0)`         |
  | ...            |                                                    |
  |----------------|----------------------------------------------------|


   Stay safe and set all your variables to zero - always, always,
always. Cheers. Prost.
