/**
 * Convert a Javascript Oject array or String array to an HTML table
 * JSON parsing has to be made before function call
 * It allows use of other JSON parsing methods like jQuery.parseJSON
 * http(s)://, ftp://, file:// and javascript:; links are automatically computed
 *
 * JSON data samples that should be parsed and then can be converted to an HTML table
 *     var objectArray = '[{"Total":"34","Version":"1.0.4","Office":"New York"},{"Total":"67","Version":"1.1.0","Office":"Paris"}]';
 *     var stringArray = '["New York","Berlin","Paris","Marrakech","Moscow"]';
 *     var nestedTable = '[{ key1: "val1", key2: "val2", key3: { tableId: "tblIdNested1", tableClassName: "clsNested", linkText: "Download", data: [{ subkey1: "subval1", subkey2: "subval2", subkey3: "subval3" }] } }]';
 *
 * Code sample to create a HTML table Javascript String
 *     var jsonHtmlTable = ConvertJsonToTable(eval(dataString), 'jsonTable', null, 'Download');
 *
 * Code sample explaned
 *  - eval is used to parse a JSON dataString
 *  - table HTML id attribute will be 'jsonTable'
 *  - table HTML class attribute will not be added
 *  - 'Download' text will be displayed instead of the link itself
