// Parse Layout String
//=======================
// opt_list: Series of characters each representing an option:
// l:  left justify component in table cell
// r:  right justify component in table cell
// t:  top justify component in table cell
// b:  bottom justify component in table cell
// w:  do not stretch width of column in which component is
//	positioned during resizing. Column width will remain wide enough to
//	contain the widest component in the column
// h:  do not stretch height of row in which component is positioned
//	during resizing. Row height will emain high enough to contain the
//	tallest component in the row
// W:  do not stretch width of component during resizing. The width
//	of the column may grow (unless constrained by w), and the 
//	component will be justified according to its layout options
// H:  do not stretch height of component during resizing. The height
//	of the row may grow (unless constrained by h), and the 
//	component will be justified according to its layout options
// 
// The options are interpreted in the constructor.

/**
 * This class parses the options string which specifies the layout options
 * for an component.
 * 
 * The layout options allow a component to be justified within the table
 * cell, and allow the initial size and dynamic resizing of components to
 * be
 * constrained. Combinations of options can be used: <b>tr</b> means top
 * and right, or north-east justification.
 * 
 * Note that the justification does not do anything special with the labels
 * of a
 * Label components: it simply sets the positioning
 * of the entire component within the cell of the <b>TableLayout</b>.
 *
 * If no options are specified for a component, all options will be
 * <em>false</em>.
