/**
 * textFormatter v.1.0 script by Laisvunas Sopauskas: http://www.classicsunlocked.net/
 * Please keep this notice intact.
 *    
 * This script takes as an input a text of a work of classics (lines should be numbered 
 * and the end of each line should be marked by <br> tag), line prefix and line name, 
 *  and outputs for each line of text html table row (<tr> tag) within which 
 *  there are two table cells (<td> tags). In one of them there is line of text with line prefix stripped and
 *  wrapped in <a> tag which has id attribute consisting from line name and line number;  
 *  in another one there is a checkbox. Such table rows after wrapping them by <table> tags  are
 *  used in ClassicsUnlocked website at www.classicsunlocked.net for publishing texts of classics.
