1. Create a new project in IntelliJ. (Name it whatever you want, such as lab4-conversions.)
2. Create a new class in the package named ConversionFunctions. (Right-click on the package you just created (under src) and select New->Java Class. Type the class name exactly as given and click OK.)
3. Delete all the source code for ConversionFunctions.java and copy in the source code found here: Lab 4 ConversionFunctions Starting Source Code.
4. Create an associated JUnit test class called ConversionFunctionsTest. See Create a JUnit Test Class in IntelliJ.
5. Delete all the source code for ConversionFunctionsTest.java and copy in the source code found here: Lab 4 ConversionFunctionsTest Starting Source Code.
6. Complete the TODOs in ConversionFunctionsTest, writing tests, and fixing bugs.

It is not required that you track this project in Git, but you may do so if you like. However, do not put this project in a public repository on GitHub.
