Labels are non-selectable user interface components that display strings or images.
Styles supported by the Label class are as follows: SEPARATOR, HORIZONTAL, VERTICAL
The SEPARATOR style causes a label to appear as a single line whose orientation can be either HORIZONTAL (default) or VERTICAL.
To create a Label, use its only constructor:
Label(Composite parent, int style)
parent: the Composite to house the Label,
style : the style.
Labels display either text or an image, but not both.
