Support - Get Temp

package cal;
/* returns the current temperature at your location. If the user's zipcode 
 * passed in (as a string) it does the same thing but about 2 seconds quicker
 * this is a heavily modified version of Professor Iacona's WebPageGetter 
 */

/* Here is an ideal point to indicate that we absolutely made portions of 
 * this with intent of greater funcionality. In this case, we would only 
 * get a user's location the first time or maybe store it in the database
 * but the point is we have two getTemp() methods and we only really need 
 * to use the slower version one time, when a user creates their account
