Updated ReadME
Refactor of rake
Adds Demo page
started adopting a strategy pattern by consolidating all of the messages, posts, user updates, and opponent updates into one data structure. Each scenario will have a key that accesses the appropriate material for that specific result of the battle instance
method that determines the situation result of each combination of the boolean values for infected, has_cure, and win, on the user. Next step: create a method to tie determine_scenario to the scenarios data structure, to ensure all messages, posts, and changes are correctly deployed.
determine_respsonses method to create the events that occur in each scenario
determine_responses method calls other methods to create the posts, update user, update opponent, and sets an appropriate message to the response variable. Some of the posts were reworded so the name of the user would come before the name of the opponent in the post. this maintains consistency necessary for the create_post method to execute the post for each instance while also inserting the correct name.
