Add enum ConstructionFrequency.
ClassBehaviorBuilder exposes a ConstructionFrequency value which describes the convention author's choice of construction frequency.
Rename *PerTestClass to *PerClass, for consistency.
Behavior builder classes collect the custom wrapping behaviors so that they can delay building, and so that the collection of wrapping behaviors can be inspected for diagnostic purposes.
Phase out now-unnecessary initialization call to ClassBehaviorBuilder.CreateInstancePerCase().
Declare array parameter as an IReadOnlyList<T> since the array need not be used as mutable.
Simplify ClassBehaviorBuilder so that the ConstructionFrequency enum can be removed.
Rename members and parameters in ClassBehaviorBuilder for clarity.
ClassBehaviorBuilder no longer combines the choice of construction frequency (per case vs. per class) with the choice of test class factory.

Change the new TeamCity command line argument from "--fixie:OptOutTeamCity true" to its inverse, "--fixie:TeamCity off".
CaseBehaviorBuilder.Wrap<TDisposable>() provides shorthand for wrapping all test cases in a new instance of the specified IDisposable type.
InstanceBehaviorBuilder.Wrap<TDisposable>() provides shorthand for wrapping all test class instances in a new instance of the specified IDisposable type.

Rename test methods for consistency.
Simplify case sorting by actually sorting by the array of Case objects rather than sorting the array of CaseExecutions.
Simplify CaseBehavior interface by including the test class instance on the CaseExecution context object.
CaseExecution, InstanceExecution, and ClassExecution context classes all inherit a common interface, BehaviorContext.
Drop deprecated Wrap<TDisposable>() behavior builder overloads.
