A dependency injection Framework
To use this package, run the following command in your project's root directory:
Manual usage
Put the following dependency into your project's dependences section:
InGen
InGen is a dependency injection Framework.
Example
/** Everything that should be injected must be a class and implement the
interface Injectable. The implementation is trivial as it is an empty
interface.
*/

}
class TestInj3 : Injectable {

}
//enum InGen;
class TestClass {
/** InGen(10) will check if there is already an instance of TestInj1 which
was constructed with the value 10. If it exists, it is returned.
Otherwise a TestInj1 is created with 10 passed to its constructor.
This created instance is additionally stored inside the InGenFactory.
