 * [ ] Take a few minutes to familiarize yourself with the [FHIR Standard](http://hl7.org/fhir/) for health data exchange. In particular you might want to read the [Executive Summary](http://hl7.org/fhir/summary.html) and the [Developer Introduction](http://hl7.org/fhir/overview-dev.html)

+### Basic Tasks:
 
 * [ ] Modify `SampleClient` so that it prints the first and last name, and birth date of each Patient to the screen
 
 * [ ] Sort the output so that the results are ordered by the patient's first name

+### Intermediate Tasks:
+
+* [ ] Create a text file containing 20 different last names
+
+* [ ] Modify 'SampleClient' so that instead of searching for patients with last name 'SMITH',
+      it reads in the contents of this file and for each last name queries for patients with that last name
+
+* [ ] Print the average response time for these 20 searches by implementing an IClientInterceptor that uses
+      the requestStopWatch to determine the response time of each request.
+
+* [ ] Run this loop three times, printing the average response time for each loop.  The first two times the loop should
+      run as described above.  The third time the loop of 20 searches is run, the searches should be performed with
+      caching disabled.
+
+* [ ] If there is enough time between runs, you should expect to see loop 2 with a shorter average response time than loop 1 and 3.
