Create a Field forEach Type of Personally identifiable information

[nelsonic]

Our objective with the fields module is to create a collection of easy to use fields that we
(and other developers) can quickly use to craft Web Apps/APIs! see: "Why?" #9

In order to streamline creating apps we need to proactively think about all the Personally identifiable information a typical app needs to store: https://en.wikipedia.org/wiki/Personally_identifiable_information

Todo

• Define the Helper Functions Encryption/Decryption and Hashing Helper Functions #10

Create the Custom Fields and Corresponding Ecto Types:

• Name Create :name Binary Field  #11
• Email Create :email_encrypted Binary and :email_hash Binary Fields  #12
• Password Create :password String and :password_hash Binary Fields  #13

as a reference Salesforce.com has these fields on thier "User" Object:

Another useful reference is the Wordpress Users, Roles & Permissions system:
