Thanks for the review @valeriepeng  Apologies for delay, had to finish up other tasks -- I've made all suggested edits that you made for src/ code and pushed those changes to my branch.

For the testing, then I recall the PKCS11Test framework not being able to return multiple PKCS11 Providers to me for testing (an array of providers) -- I thought editing the framework for such a use case would be useful but perhaps I'm better off just writing a customized test. I'm going to take a stab at that and will re-submit a test edit.

Apologies for including the Login.java/ Login.sh edits - they were old left over edits from testing efforts before moving on to develop the new MultipleLogins.java test.
