//Join TextFrames v.1.2 -- CS,CS2
//>=--------------------------------------
// When Adobe came out with the new CS text engine,
// the text fields in documents saved in an older format were
// often broken into "sub" fields.
//
// This script is a rudimentary tool to help 
// rejoin the broken text fields.
//
// It collects text from any number of selected (non-grouped) textframes 
// and aggrigates them into a single text frame.
// the order is based on relative x,y coordinates.
//
// If a selected text anchors vertical coordinate is the same as the next one, 
// text areas are assumed to be on the same line.
//
// If a selected text anchors vertical coordinate is different, 
// the text areas are assumed to be sequential lines, 
//
//
// THIS script WILL NOT make any attempt to maintain visual integrety of 
// character placement. It will only join the fields for easier editing,
// but sometimes, just this little bit is a HUGE time saver.
