Subject: [PATCH 06/21] Update SampleDataUtil#getSampleApplication() method.

Currently, the method is being used to create Sample Data that will
be used to populate InternApply's application list.

This method is only called if an existing internapplymemory.json
file is not detected in the data folder.

The Sample Data is a hard coded set of applications. This means that
the Interview Slots created are generally going to be irrelevant at
some point.

Let's implement a way to generate Interview Slots that are more
useful.

To do this, we want to check for the LocalDateTime.now() of the
local machine and use that to generate our Interview Slots.

This ensures that no matter which user is using InternApply or when
they are using InternApply, the Sample Data generated (if needed)
will be relevant relative to the actual current local date time of
his/her machine.

 SoC InternApply (SIA) is a **desktop app for managing internship applications, optimized for use via a Command Line Interface** (CLI) while still having the benefits of a Graphical User Interface (GUI). If you can type fast, SIA can get your internship application management tasks done faster than traditional GUI apps.
 
+With SoC InternApply, you can easily add an application, edit it later on if there are any changes needed, find the applications based on keywords and also sort them based on priority, interview date and much more! All while not having to worry about saving or storing your applications as this is done internally and automatically by SoC InternApply. 
+
+Ultimately, with SoC InternApply, you can worry less about the administrative tasks and focus more on preparing for the interviews themselves!

 ## FAQ
+**Q**: How do I know where my internship applications data is stored?<br>
+**A**: Please locate where SoC InternApply is being stored on your computer. You will see a folder named `data` found in the root folder of the application (the folder containing SoC InternApply) Inside the `data` folder, you can find a data file named `internapplymemory.json`, which stores all the applications.

Subject: [PATCH 15/21] Update ParserUtil#parseTags() method.

Currently, the method simply checks if the Collection of Strings
passed to it is null or not.

This means that even a Collection of empty Set<String> would pass
this check as a valid input.

Let's change this since an empty Set<String> not be meaningful and
should be rejected.

We simply include an if-else statement that determines if the
Collection passed in is an empty Set<String>.

EditCommandParserTest#parse_resetTags_success() has been changed to
parse_resetTags_failure() since the behavior that it is testing for
no longer exists and "t/" as an empty input is now invalid.

+Sorting paramters: 
+- `name` : Sort by name of the company in alphabetical order starting with A in ascending order.
+- `interview` : Sort by interview date of applications starting with the latest earliest date.
+- `piroity` : Sort by piroity in the following order - HIGH, MEDIUM, LOW.
+- `status` : Sort by status in the following order - ACCEPTED, REJECTED, INTERVIEWED, APPLIE and NOT_APPLIED.

+* If optional fields (i.e. interview date and time, piroirty, status) do not exist in that certain application, that application will be move to the bottom of the sorting order. If there is more than one of such application, it will be sorted alphabeticaly.
+
+Order by:
+- `asc` : Order by ascending.
+- `desc` : Order by descending (reverse order of ascending).
+
+Examples:
+* `list interview desc`
+* `list name desc`, running this will output:
