| :: Reference :: Columns & Rows ::Columns and rows are specified by three parts:
		For example, you can specify that a column is left aligned, 
	has an initial size of 50 Dialog Units and grows: 
	new ColumnSpec("left:50dlu:grow");a mandatory initial size
		an optional default alignment
		an optional resizing behavior
	 Resizing BehaviorColumns and rows can grow if the layout container becomes larger 
	than the preferred size. By default, columns and rows won’t resize. 
	The extra space is distributed over the columns and rows that 
	have a resize weight larger than 0.0, where each column gets a space 
	proportional to its weight.String RepresentationsString representations for column and row specifications
	can be used in the FormLayout constructors as well as in classes 
	ColumnSpec, RowSpec.
columnSpec     ::= [columnAlignment:] size [:resizeBehavior]
rowSpec        ::= [rowAlignment   :] size [:resizeBehavior]
resizeBehavior ::= NONE | GROW | GROW() | G()
 Examples
new ColumnSpec("16px");
new ColumnSpec("left:16px");
new ColumnSpec("left:16px:grow");
new FormLayout("right:max(50dlu;pref), 4dlu, max(100dlu;min)", 
               "p, 3dlu, p, 3dlu, fill:200dlu:grow");
