/**   This class models a time.  
 *	  Author:  Linda Crane, edited by Anu Thomas
 *	  Data fields:  hour: int - values of 0-23 for 24 hour clock 
 *                  minute: int - values 0-59 
 *    Methods:  default constructor
 *              initial constructors
 *				getHour: int - return hour value
 *              getMinute: int - returns minute value
 *				setHour (int) - sets hour to parameter value
 *				setMinute (int) - sets minute to parameter value
 *				isEqual (Time): boolean - returns whether current time object has same time as parameter
 *          **  isGreater (OurTime):boolean - compares two OurTime objects and returns true if current object (this) is 
 *                                            greater than the parameter object; else returns false
 *				toString:String - displays values of time to String
 *				readTime(Scanner, char) - prompts user (if  char is 'k') 
 *                                       to enter values for data fields from Scanner parameter
