  Name 			    :  bearng 
  Description 	:  calculates the bearing(angle) between given two lattitude and 
  			   	       longitude points 
  Parameters  	:  lat and lng are point one lattitude and longitude respectively 
  			   	       lt and ln are point two lattitude and longitude respectively
  Return 			  :  This function will return the bearing(angle) between given two 
  			           lattitude and longitude points
