This is currently caught elsewhere as well, but provides defense-in-depth
for the situation that time bounds in LTL are supported later on.
Bounds on temporal operators don't have the same semantics in CTMCs
as for discrete-time models.

If the expected result specified via // RESULT
is an error, we treat a PrismNotSupportedException just
as any other ordinary exception. This allows verifying
the content of a PrismNotSupportedException error message.
Otherwise, we do the usual special handling as before.

There's actually JDK library functionality for a hash map that
uses object identity instead of .equals(), making PlainObjectReference
unnecessary. Use IdentityHashMap instead.

Previously, subformulas were computed by a DTMCModelChecker
in the embedded DTMC, yielding wrong results. Now, maximal
state subformulas are checked via the CTMCModelChecker and
replaced by labels before calling the LTL model checking
routine on the embedded DTMC.

The labels encode the satisfaction sets of the subformulas. This method can be
used to do the standard PCTL* recursion step, i.e., computing Sat(phi) and replacing
phi with an atomic proposition a_phi in the formula.

When building a model from the GUI with the explicit engine, constant were sometimes not
updated correctly:
(1) Open xprism, switch to explicit engine
(2) Load a model with undefined constants, e.g., brp.pm
(3) Build the model, setting constants (e.g., 2 and 3)
(4) Build the model again, setting *other* constants (e.g., 22 and 3)
In step (4), the log file reflects the changed constants,
but the generated model has the same number of states as
in step (3) and is fact built with the constants of step (3).
The cause:
If the PRISM file is not reloaded, then the currentModelGenerator
remains the same. In ModulesFileModelGenerator.initialise(), called
from setSomeUndefinedConstants() in step (3), the modulesFile is
overwritten with the modulesFile where the constants set in step (3)
have been replaced in the AST with the concrete values.
In step (4), there are no more AST-elements with undefined constants
and hence the modules file does not reflect the changed constants when
the constants in the constant list are changed.
The fix is to keep a copy of the original modules file in the
ModulesFileModelGenerator which is freshly deepCopyied and
processed in the subsequent calls to initialise().
Regression introduced in SVN r10996 when switching to the
ModulesFileModelGenerator infrastructure.

Now, double-clicking on a property will open the editor
for that property. Double-clicking on an empty area of the
property list will open the "new property" editor.

This allows a (symbolic) model checker to serve as the parent PrismComponent
and provides access to the settings and log files whenever a ModelChecker
is available.

We have to clear the StateValues vector of the initial distribution
to avoid a reference leak when using the MTBDD engine. E.g., when
doing
prism prism-examples/dice/dice.pm -ss -mtbdd
