	Builds navigational links inside content module,
	specifically, inside div element with specific id "cyclediv".
	If element is not found - nothing is done.
	If element is found, its inner HTML is used to determine which link definition
	should be used (stored in the global array "cn_array").
	For this purpose the text inside the div element should be one of the numbers used in
	one of the definition cases.
	Links are separated by globally declared variable "separator_"
	Styles for the div element can be defined in existing CSS file.
*/

//Global variables:
var separator_ = " | ";
var cn_array = new Array();

//Load array with navigational schema
//Elements are separated by pipe "|"
//Each array element has 4 components separated by pipe "|":
//	first - number is the navigation group number (type);
//	second - menu title;
//	third - menu url
//	frouth - link target (leave empty for same window)
//Array contains all links from all groups. They'll be mached one by one with the type passed
//from the div on the page

/*
	Array declaration example:

cn_array.push("1|Link to Page 1|page1.htm|");
cn_array.push("1|Link to Page 2|page2.htm|");
cn_array.push("2|Link to Page 1|pageA1.htm|");
cn_array.push("2|Link to Page 2|pageA2.htm|");
