1. Assigned the constructor "com.huanli.ui.ScrollBars" which is for
referencing static variables to a variable named STATIC so that the code
look cleaner and is easier to maintain.
2. Changed the ids of the added elements. Added the total number of
instances to the ids so that there won't be id collisions.
Correct the constructor of the class by explicitly assign the
"funcConstructor" to the prototype's constructor property.
Made changes according to the the changes in the com.huanli.lang.OO
class' "defineClass" function.
Removed the CSS class "transition". "Transition" is now added by calling
the "css" method on an element.
1. Reformatted.
2. Added a check on the arguments in the "initializer" function.
