The following are the valid justifications for a field:
NO_JUSTIFICATION
No justification is to be applied to the field. In practice, this is the same as JUSTIFY_LEFT.
JUSTIFY_RIGHT
The field will be right justified. That is, the end of each line will be butted up against the right hand side of the field.
JUSTIFY_LEFT
The field will be left justified. That is, the start of each line will be butted up against the left hand side of the field.
JUSTIFY_CENTER
The field will be centre justified, padding will be applied to either end of the line to make the line centred in the field.
