Gradle Kata: Task creation

Setup

Run source setup.sh

You are in a newly created Gradle project. Examine the available tasks using ./gradlew tasks
Create your first task by copying the following code to build.gradle
```
task hello {
    println "Hello, friend!"
}
```
Run ./gradlew
Q: Did Gradle print Hello, friend!? What happened? Inspect the full output from the command
Run ./gradlew hello
Q: Was the output as expected?

Add a Group and a Description to the task:

task hello {
    group "Greeting"
    description "prints a warm greeting"
    
    println "Hello, friend!"
}

Run ./gradlew tasks
Q: Is your tasks visible? In the correct group? And with the correct description?
