Detailed Description

We need to have something that allows one plugin stack to access another plugin stack, so this represents a instantiation of each plugin stack. It also keeps common state: user credentials, security context, and run-time parameters (see set)

Note:

Assume a StackInstance (and every instantiated interface under it) is NOT thread-safe. This means, a StackInstance must be used by only one thread at the same time.
