[edutex] Some demo files and the edutex package documentation

For PDF in for credit mode, if the processing of the test is to occur on the client-side via 
JavaScript, then security is an issue unless a third party application is used, such as 
FDFMerge, which can also be used to merge FDF data with a PDF and save. Looking at the 
docs of fdfmergelite, you can encrypt, set the PDF to no print, no modify, no copy (and 
paste).  

It's now clear what we'll ultimately do about processing the test, if it is done server-side, or 
not.
