A `List<Type> StateHistory` property that will hold a list of the previous 
states with the latest state at `StateHistory[0]`.

Also a GoBack method that will perform a transition from the current state back 
to the previous state, overriding valid triggers etc. This should come in 
especially handy when building wizards etc.

Offer a possibility to have the state machine serve up new target state 
instances on each transition.

What steps will reproduce the problem?
1. view BehaviourTests.cs. lines 305, "VerifyStateSingletons"
2. note line 289 "// No setting of the value here, Singleton should be the 
default."
3. note line 307 "(sm.CurrentState is CountingState) && ((sm.CurrentState as 
CountingState).EnteringSelfCount == 2),"
3.

What is the expected output? 
"// The CurrentState should be a singleton and re-used, meaning that 
CountingState.EnteringSelfCount should be 2"

What do you see instead?
"// The CurrentState should have been freshly created, meaning that 
CountingState.EnteringSelfCount should be 1"

What version of the product are you using? On what operating system?
1.2.0.0 - got 2015-01-07

Actually it is not a bug, but I'd like to use this library in iOS

What steps will reproduce the problem?
1. Call SolidMachine.Transitioned += method; in iOS device

What is the expected output? What do you see instead?
No error expected. but the error occurs in iOS Device as follows.
Attempting to JIT compile method '(wrapper managed-t-native) 
System.Threading.Interlocked: 
CompareExchanged(Solid.State.TransitionedEventHandler&,Solid.State.TransitionedE

What version of the product are you using? On what operating system?

I Tried to get your email address but it didn't show. I tried guessing it but 
just in case that was wrong... here is a patch to build SS as a PCL. It was 
almost trivial to do but it would be nice to see it in nuget.

To avoid having a state history that grows into thousands of entries, a 
StateHistoryTrimThreshold property can be introduced. When the state history 
contains more entries than the threshold, 10% of the oldest entries are deleted.

At application shutdown or when the state machine is no longer needed, it would 
be a natural thing to be able to exit the current state without entering a new 
state. A SolidMachine.Stop() method is a natural way to do that.
