task_list.rb

# Today we'll be creating a Task List for an individual
# who has a lot of errands and tasks to complete and multiple
# locations or stores to go to in order to complete them.

# Create a class for a Task List.

# All TaskList instances should have an owner and a dute date
# passed in on creation. For instance, our owner could be "Tyler"
# and his due date would be "Sunday". The owner should not be
# changeable but you should be able to read it outside of the class.
# The due date should be readable and writeable outside of the class.

# We may have multiple locations to go to in order to complete our
# tasks, for instance we may need to go to Target to pick up batteries.
# Create a list instance variable which can hold the location and tasks at
# each location. It should be empty on creation.

# When we think of a new location we need to go to, we'll need to save
# it in our list and set it up to hold multiple tasks. Create an instance
# method that will save the new location to the list with the ability to
# hold multiple tasks. If the location already exists in our list, notify
# the user that the location is already on the list.

# When we add a new task to the list, we'll need to also say which location
# the task should be completed. Create an instance method to save a task and its
# location to the list. If the location doesn't exist in the list yet,
# we'll need to create it, and then add the task. If the location
# already exists, then we'll need to check if that task already exists
# for the location. Check if that tasks is in our records for the location,
# if it's not, add it. If the task already exists, notify the user
# that the task is already on their list!

# Congrats, you completed a task - cross it off your list! Create an instance
# method to delete a task off it's location records. If the specified
# location includes the task, delete it. If the specified location
# does not include the task, notify the user that they don't
# have that task on their list.

# Man, you sure have a lot to do! Print out your list in a user
# friendly way, printing each location and then each of the tasks
# needed to be accomplished there below it. Like the following:
#
# At Target:
# - pick up batteries
# - get new toothpaste
# At pet store:
# - pick out new chew toy
# At post office:
# - mail Grandma's birthday present
# - buy new stamps

# Uh oh, have you done everything on your task list by the due date?
# Create a predicate instance method is_past_due? that uses the current
# day as an argument and checks to see if your task list is past due.
# You'll need to compare the days of the week to each other in some way.
# Don't forget that if you have no tasks on your list, then nothing is past due!
