Add a new Fruit class with Fruits helper objects.

They will live in the new bobsdelights package. This will serve
as an example of how to perform various kinds of imports.
Add a simple import example.

Directly import a class by name, just as you would in Java.
(minus the trailing semicolon, of course)
Add another import example.

You can import all the members of a package by using ._
The reason why this differs from .* as in Java is because * is a
valid identifier in Scala so it couldn't also be used as a
package/class name wildcard.
Add another import example.

This example is analogous to importing a class' static fields in Java.
Add an example showing Scala-specific import features.

Imports can appear anywhere, not just at the beginning of a
compilation unit. And, you can refer to arbitrary values.
For example, here, we import all of the members of the Fruit
object that's passed, and it's not a singleton object, either;
neither are the imported members static.
