/**
 * Create a DynamoDB item from the values specified in the account parameter. The names of the attributes in the
 * item should match the corresponding property names in the Account object. Don't add attributes for fields in the
 * Account object that are empty./*from   w  w  w.j  a  va 2  s. c  o  m*/
 * 
 * Since the Company and Email attributes are part of the table key, those will always be provided in the Account
 * object when this method is called. This method will be called multiple times by the code controlling the lab.
 * 
 * Important: Even thought the Account.Age property is passed to you as a string, add it to the item as a numerical
 * value.
 * 
 * @param ddbClient The DynamoDB client object.
 * @param tableName The name of the table to add the item to.
 * @param account The Account object containing the data to add.
