Add a constructor to the Frog class that accepts a tongue length parameter value.

Most of the previous video is dedicated to the topic of class constructors, so if you are confused it might be a good idea to just watch it over again from the start.

In the previous video Jeremy shows how to create a constructor for the Map class that takes a width and height parameter. The code required for this challenge is practically identical with the one shown. The only differences being in the names involved and the fact that in the challenge there is only one parameter (tongueLength) rather than two like there was with the Map constructor.

As a remainder the Map constructor ends up looking like this by the end of the video:

public Map(int width, int height) { // Take width and height as parameters
    Width = width; // Assign Width field to width parameter 
    Height = height; // Assign Height field to height parameter 
}

I added some commentary to clarify how it works, the Frog class constructor will end up looking pretty similar by the end of the challenge.
