 During the script execution CS-Script always injects a little object inspector class 'dbg'. This class contains static
 printing methods that mimic Python's 'print()'. It is particularly useful for object inspection in the absence of a
 proper debugger.

 The major changes in this release are around improved support for working with external compile engines in CodeDom evaluator mode. Now both, CLI and CSScriptLib APIs allow automatic download and deployment of the latest .NET compilers (nuget packages) on the target system so the user does not have to install the complete .NET SDK.
