Unit tests for Grrr-sc

Evaluate the following in SuperCollider:

GRControllerTests.runAllTests;
GRViewTests.runAllTests;
GRContainerViewTests.runAllTests;
GRTopViewTests.runAllTests;
GRButtonTests.runAllTests;
GRToggleTests.runAllTests;
GRKeyboardTests.runAllTests;
GRMultiButtonViewTests.runAllTests;
GRMultiToggleViewTests.runAllTests;

GrrrTest-sc requires Grrr-sc and the Test-sc library. This code has been developed and tested in SuperCollider 3.8.0.

Install the Grrr-sc and Test-sc dependencies.

Copy the GrrrTests-sc folder to the user-specific or system-wide extension directory. Recompile the SuperCollider class library.

The user-specific extension directory may be retrieved by evaluating Platform.userExtensionDir in SuperCollider, the system-wide by evaluating Platform.systemExtensionDir.
