// Elastic tabstop experiment section. Not ready for general use by any means
// the text/tabwriter package implements elastic tabstops, but this package
// assumes that all chars are the same width and that text needs to be rescanned.
//
// The frame already distinguishes between tabs, newlines, and plain text characters
// by encapsulating them in measured boxes. A direct copy of the tabwriter code would
// ignore the datastructures in the frame and their sublinear runtime cost.
//
// A few cases need to be handles for elastic tabstops:
//
// Insertion:
// 	An insert always creates a new box, this box can take on the form '\n', '\t'
//  or be part of the plain text character set which for this purpose is the set
//  of characters not equal to '\t' or '\n'. A successful insert operation runs
//  to completion and results in a net gain of runes (not taking into consideration
//  the runes which run off the frame and are deleted). An insert never subtracts
//  of boxes assuming that all characters stay on the frame. There are now a few
//  cases:
//
//  1. The insert contains plain text characters
//		This is already a non-trivial case. Plaintext characters can move a column of
//		text far enough to extend the range of the column's tab stop. The procedure then
//		is to seek forth and determine if a tab follows the insertion point. This can be
//		completed in sub-linear time, as plain text boxes are merged into one before the
//		start of a hard newline or soft wrap (when a box width exceeds frame.r.Max). The
//		soft line wrap property of boxes may aggregate the runtime performance of this
//		implementation by containing sparse newlines. In this case we consider an algorithm
//		that gives up and favors performance over elasticity. Elastic tabstops have little
//		use in binary files anyway and we probably want to give users the opportunity to turn
//		them off. The seek forth operation scans forward and locates the first newline, while
//		counting the occurence of \t boxes and measuring their width. The maximum width column
//		is tracked as well. The seek forth operation terminates whenever a column-less line is
//		located (formally defined as a run of boxes seperated by a newline containing no \t boxes
//
