You have seen most of the code needed for this class in previous classes we have created. The
private attributes (textField, life, and lifeCount) and constructor parameters (text, textFormat, x, y,
and life) have been discussed previously. Aside from accepting parameters and assigning them
to the private attributes, the constructor also creates the textField with the passed in text value
and calls the addChild method to place it on the stage display list.
