* In Alepha, there are several "grades" of exception types which can be thrown. The grade of
* an exception is "branded" into its name as the last word in camel case.
*
* * `Throwable`: All exceptions inherit from this interface. Catching this will
* * `Exception`: All exceptions inherit from this interface. Catching this will
* catch anything which is part of this system. Normally you just ignore this grade.
* Code that needs to catch *everything* should not catch `Throwable`, but `catch( ... )`
* instead.
* Code that needs to catch *everything* should not catch `Exception`, but `catch( ... )`
* instead. `Exception` is the mechanism by which various situations are reported.
* For comparison, Java calls this class `Throwable`.
*
* * `Notification`: When a thread is cancelled using interrupts, all exceptions thrown
* * `Condition`: An out-of-band message from functions which notify their callers of
* new information that affects the ability to fulfill the common case expected
* result. Note that this kind of `Exception` is not considered a contract `Violation`.
* This exception can be thrown as part of normal program operation -- it is a control
* flow device.
*
* * `Notification`: When a thread is cancelled using interrupts, all `Exception`s thrown
* to do so are derived from this type. Alepha threads are setup to catch and discard
* exceptions of this grade in the thread start function.
* `Exception`s of this grade in the thread start function. It is legal to catch `Exception`s
* of this type type and silence it; however, `Notification` typically means that the
* target thread needs to change its behaviour. (Note that `ThreadInterrupt` is entirely
* independent from the Alepha exception hierarchy -- this helps ensure that the thread
* termination mechanism works correctly.)
*
* * `Exception`: This is the exception grade you would typically want to recover from.
* Catch this grade, typically. They should contain sufficient information in their
* * `Error`: This is the exception grade you would typically want to recover from.
* Catch this grade, in most circumstances. They should contain sufficient information in their
* data pack to facilitate a proper programmatic recovery. All exceptions of this grade
* will also have `std::exception` as one of its bases, thus code which is unaware of
* Alepha exceptions, but handles basic standard exceptions cleanly, will work just fine.
* When an `Exception` models something that the standard library models, such as
* `std::bad_alloc`, then that `Exception` will be eligible for catch by that base as well.
* When an `Error` models something that the standard library models, such as
* `std::bad_alloc`, then that `Error` will be eligible for catch by that base as well.
*
* * `Error`: This exception grade represents a form of moderately-unrecoverable condition.
* The `Error` grade typically indicates a condition that prevents the current thread or
* * `CriticalError`: This exception grade represents a form of moderately-unrecoverable condition.
* The `CriticalError` grade typically indicates a condition that prevents the current thread or
* program state from being easily transitioned to a recovered state. However, a very
* large state transform, such as an unwind to the top-of-thread-callstack handler, may
* be able to recover. For example, no more available operating system file handles.
