Description 

Author

This package provides a trait to implement the singleton design pattern.

The trait provides functions that return a new instance of the class if none was created so far, or an already created instance of the class otherwise.

It may also force creating a new instance of the class even if another was created.

The trait uses reflection to call the class constructor passing any arguments as a list or as an array.
