add tests for the 'customer' role.

NOTICE: Programmers are REQUIRED to REVIEW AND SOLVE the bugs listed
in <bug_report_v3.0.doc> and <bug_tracking_v3.0.xlsx>.

This test suite examines the 'customer' role. Included are the following
3 files:

	Tests/Week_7/Yan_Shimin/customer_bug_report_v3.0.doc
	Tests/Week_7/Yan_Shimin/customer_bug_tracking_v3.0.xlsx
	Tests/Week_7/Yan_Shimin/customer_test_suite_v3.0.xlsx

The contents of these files are:

<bug_report_v3.0.doc>: this document lists all the 19 bugs detected so far
		       in the 'customer' module. It describes the location
		       as well as symptom of a bug.
<bug_tracking_v3.0.xlsx>: This table briefly lists all bugs that
			  <bug_report_v3.0.doc> mentions. It REQUIRES ALL
			  PROGRAMMERS to solve bugs of their code, and after
			  that, FILL IN the 'RESOLUTION' and 'STATUS' columns.
<test_suite_v3.0.xlsx>: This test suite lists all the test cases we employed
			in testing the 'customer' module.
			Programmers are encouraged (but not necessary) to take
			a look at this table.

Thank you!
