User

Started to create the user model, db and spec.

Couldn't teste guard because I have a syntax problem:

/Users/my_Mac/.rvm/gems/ruby-2.1.1@foodies_cube/gems/activesupport-4.1.4/lib/active_support/dependencies.rb:241:in `load': /Users/My_Mac/foodies_cube/spec/models/user_spec.rb:36: syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError)
where did you get this code from?
