USGRecommender 注释错误

* ###special notes###
 * 1. prediction for all user, please set:
 * data.testset.path = poi/Gowalla/checkin/Gowalla_test.txt
 * and delete the para setting for "rec.limit.userNum" in rankgeofm.properties
 *
 * 2. prediction for small user set like userids in [0, 100],
 * in rankgeofm.properties, please set:
 * data.testset.path = poi/Gowalla/checkin/testDataFor101users.txt
 * rec.limit.userNum = 101
 * In EntropyEvaluator and NoveltyEvaluator, you also need to reset the variable "numUsers" = your limited userNum

USGRecommender 里注释这几个 properties 应该写错了，应该是 usg-test.properties
