##Objectives: Create a checkout method to calculate the total cost of a cart of items and apply discounts and coupons as necessary.
Dr. Steve Bruhle, your green grocer, isn't ready, but you are!
##Skills: any?, all?, none?, each, map/collect
##Instructions: Code generates a random cart of items and a random set of coupons. Implement a method checkout to calculate total cost of a cart of items and apply discounts and coupons as necessary.
##Objectives:
Implement your own version of any?, all?, and none? to evaluate your pokemon team.
##Skills: any?, all?, none?, yield, blocks
##Instructions: Code contains a set of statements about a randomly generated pokemon team Implement and call your own versions of any?, all? and none? so that the statements are true.
##Objectives: Use String, Hash, Array, and Enumerable methods to decode a string and discover a secret message
INSPIRATION: http://www.youtube.com/watch?v=Wj1d85CLDOQ
##Skills: String.split, Array.each, Hash.each, Hash.sort_by, Range.to_a, Array.reverse, Array.push, Array.join, String.gsub, Array.index
##Instructions: Comments explain steps to manipulate string
| i have [["a", "b", "c"],["a", "b", "z"],["d", "e", "f"],["d", "e", "p"]] | |
| ok i need to buil {a=>??,d=>??} | |
| THEN i need to build {a=>b, d=>e} | |
| THEN i need to build {a=>{b=>??},d=>{e=>??}} | |
| THEN i need to build {a=>{b=>[]]},d=>{e=>[]]}} | |
| ** maybe make [c,z] and [f,p] | |
| THEN i need to build {a=>{b=>[c]]},d=>{e=>[f]]}} |

| #1. create a class called Project | |
| class Project | |
| #3. make the instance variables accessible by dot notation EXCEPT for date updated | |

| Classes are blueprints. Objects are known as 'instances' of these classes. | |
| Classes are where we define all variables and methods. | |
| Instance variables (@var_name) and instance methods (def method_name) belong only to objects and are accessed using dot notation (Object.name) on an object made using 'Class.new'. | |
| Class variables (var_name) |
