Description

This ticket will add the import function to be used within a let expression to import Streaming Expression and Stream Evaluator classes from the classpath and bind them to function names:

let(hello=import("com.mycompany.HelloWorld"),
    a=hello())

In the example above the Stream Evaluator is bound to the function name hello and invoked below using the function name hello.
