DemoPlugin - Get Session name

I am trying to figure out all the possibilities with the SDK by analyzing the DemoPlugin code and trying to read the (very terse) API documentation. It always helps to have examples with documentation ....

Anyway I made good progress but there is one thing I can not figure out: How do I get my Session Name or Session home directory ? The only paths I can find exposed in the variables are temporary publishing file path and the plugin code directory.

Without knowing from which session my processed image comes, there is really not much that can be done with the SDK.

Any ideas ??'

Thanks, Jozef Dassen
