Decrease visibility of classes in Jimple EvoSuite package

[JSAbrahams]

Classes that do not implement the interface should not be public. Therefore, these have been made internal. Their functions have also been made internal, and some have been made private.

The ValueIsNotLocalException has been made internal as this should also not be part of the interface, it is only thrown.

The exception classes should be private

[JSAbrahams]

@fwdekker Yes but they are used in the tests, so they need be internal. But I do agree, usually they should be private. In general I quite dislike that methods often can't be private for testing purposes. I know that tests should ideally only test the interface of a class, but still.

[fwdekker]

Ah, alright then.
