Ping Identity Interview: Take Home Coding Exercise
Engineer Level Exercise

System Requirements
-------------------------------------------------------------------------------
-Java 1.6, 1.7 or 1.8
-Maven 3.x

Package Contents
-------------------------------------------------------------------------------
-This README file
-A pom.xml file (for Maven)
-A src directory with java source files
-A public directory with static web content

The Exercise
-------------------------------------------------------------------------------
Imagine that you are implementing a web application that needs to gather data 
from multiple sources and display it to a customer. In this exercise, the
objects are groups of People, with 4 attributes: first name, last name, age,
and height. There are two sources of data, found in src/main/resources in the
project (people.txt, people.json). You must read in the data from both files,
combine it, and display in on a web page. 

The data must be sortable in ascending/descending order by each attribute from the
controls on the web application. The customer also wants to be able to add a new 
person. Please see public/fuji_interface.pdf for a sample screen mock.

Please note, this exercise is left deliberately vague. 
Feel free to implement the requirements as you best see fit.

Key Requirements/Givens:
-------------------------------------------------------------------------------
* Application should work without page refreshes.
* Data must be read in from the files provided. Added users do not need to be saved to disk 
(but should be stored in memory server side).
* Web application must consume a server side rest api via the provided controller.

* 3rd Party libraries are allowed. Be prepared to explain why/how they are used.
* Unit tests can be added.
* Code should be commented appropriately.
* Alternative build approaches can be used (Ant, Gradle etc).

Building the project
-------------------------------------------------------------------------------
To build the project, perfom a mvn clean package from the root directory, where
the pom.xml is located. To run the web app, perform mvn spring-boot:run. This will
start a web-app on localhost:8080. You can see the sample index.html at
localhost:8080/index.html. You will notice that the "Good Luck" link is hooked to 
Controller.java. There is lots of documentation online for Spring Boot / MVC 
web applications, if you run into trouble. 

Please return your implementation (or whole package) prior to the provided
deadline.
