Uleat: Probable fix for 'Debug Assertion Failure' in Client::GarbleMessage() when calling the 'isalpha' macro.
ref: https://connect.microsoft.com/VisualStudio/feedback/details/932876/calling-isdigit-with-a-signed-char-1-results-in-a-assert-failure-in-debug-compiles
== 03/29/2015 ==
Secrets: Identified the Target Ring fields for RoF/RoF2.
Secrets: Added a perl accessor for the last target ring position received from the client. Usage: $client->GetTargetRingX(), $client->GetTargetRingY(), $client->GetTargetRingZ()
