notnull.cpp was a test to see what null or nullptr returns.

udpated tasks.json to display timestamp for executable creation.
More useful errors were tracked and are now displaying in pdfHummusTest1.
We spent about 3-4hours to finally capture some errors related
to StartPDF.
Microsoft was actually creating our file, but was saving it somewhere else.

 Successfully created a log file for errors using Gal's LogConfiguration structure. We are not sure what errors he actually keeps track of so we have to hunt for errors to log.
-Cleaned up tasks.json so there isn't a bunch of unuseful text such as "terminal will be resused message" or "execting tasks" messages. This needs to be cleaned up a little bit more
-and more useful information needs to be added. For instance, failed does not print on the same line inside the terminal.
 
-Kyle states: add one more line of code to state that your program worked as a work around for the "press any key" "error".

+Unsure if we can have both text and a picture on the same page for the PDFWriter. Need to possibly create a second page, one with text on it, then one with the picture on it.
+Third page we could try and create it with both. This may have something to do with how pageContentContext works??? Anyways, the image is working now and the text is commented out.
