Added base-class to start the appdomain layout.
Added "remote" projects to represent the assemblies to load into each AppDomain; also created a MarshalByRef object to load them.
Added initial timer-intervals for each external library.
Created the simulated "work" for the NormalLibrary.
Added the heavy, memory-intensive, simulated work for the MemoryAbusingLibrary.
Converted IRemoteObject into an abstract class (opposed to an interface) to implement the common AppDomain polling.
