Let's tweak the docs/README.md (which is used as the user guide)
to fit Duke better. Specifically,

1. mention product name in the title
2. mention adding a product screenshot and a product intro
3. tweak the flow to describe feature-by-feature

… add task to list

…ethods.

…nd Event constructors.

…modifies control flow

* branch-Level-7:
  Writes task list into file after list is modified.
  Initializes task list from hard drive when chatbot starts up.

* branch-Level-8:
  Adds ability for chatbot to understand dates and times.

* add-gradle-support:
  Bump gradle and lib version
  Add Gradle support
  docs/README.md: Tweak document template

* branch-Level-9:
  Adds a find method that can filter the task list by a keyword.

* branch-A-JavaDoc:
  JavaDoc modified to follow coding standard
  Added JavaDoc to most classes and methods

# Conflicts:
#	src/main/java/virtue/VirtueTask.java
#	src/main/java/virtue/VirtueTaskList.java

* branch-A-CodingStandard:
  Code modified to follow the coding standard

# Conflicts:
#	src/main/java/virtue/Ui.java
#	src/main/java/virtue/Virtue.java
#	src/main/java/virtue/VirtueTaskList.java

* branch-A-CheckStyle:
  Finds coding style violations and resolves them

* branch-Level-10:
  Incorporates a GUI into the chatbot.

The sandwich and indent features are obsolete due to the new GUI.

The applyCommand method is better not without
a String output because it is public.

Let's
* remove the sandwich and indent methods in Virtue class
* remove its usages
* create a resultMessage field in Command class
* make the applyCommand method set the Command resultMessage

Adds assert checks to the code

* master:
  Adds assert checks to the code

Refactors the code to improve code quality.

* 'master' of https://github.com/sarjinius/ip:
  Refactors the code to improve code quality.

The mark, unmark, and delete commands
can be applied to several tasks.

Adding this features makes it more convenient for the user.

Let's,
* update the getIndex method to accept multiple indices
* update the markTasksAsDone, markTasksAsNotDone, and deleteTasks
  methods to accept an array of indices

* branch-C-MassOps:
  Provide a way to perform commands on multiple tasks

Several lines in the getIndices method were taken and modified from several websites.

Let's,
* add comments citing the sources for the code

A good product screenshot showcases the product in its full glory.

Let's,
* produce a sample run with realistic data
* take a screenshot of the sample run
* add the screenshot to the docs folder

A user guide is needed for users to understand how to use
the chatbot's commands.

Let's add the command details and examples, together with
the Ui.png image, to the user guide.

When a user inputs an empty description or index,
or an index out of range, the user must be alerted.

Let's,
* check if a description is not entirely whitespace
* check if all indices are in the appropriate range
* alert the user if the conditions are not satisfied
