Per https://github.com/exercism/docs/blob/81399dc1c87e384be9fada77f599df38f795691d/contributing-to-language-tracks/exercise-readmes.md#exercise-readmes

The contents of this file will be included in each of the README.md
files that are delivered along with the test suites in the exercism
problems.

It's probably useful to provide a generic description of how to run
the tests, as well as a link to the language-specific help page or
useful documentation.

This will cause the correct directory structure to be created when fetching.

Gradle can be run directly on Mac/Linux/Windows and
auto-download dependencies (much like sbt for Scala),
as well as simplify IDE integration.

Add appropriate .gitignore for this sub-tree.

For developers, to add a new exercism:

    cp -r _template new-exercism
    # create test in new-exercism/src/test/java/SampleTest.java
    git add new-exercism

Users will be able to just run "./gradlew check" to run tests.

To use this template to create a new assignment,
simply cp _template to the name of your new assignment
and drop in the appropriate tests.
