parameter.storeInLog() is intended to only log changes to a
parameter's value. However, at present, assignment of NaN to a
parameter can lead to excessive logging if the parameter's
.value is already NaN.
This is because the current test all(v(:) == o.value(:)) is
false if both v and o.value are NaN.
This can become a problem if a function string, evaluated every
frame, evaluates to NaN leading to a NaN being logged every frame.
This change proposes to use isequaln(v(:),o.value(:)) in place
of the existing all(v(:) == o.value(:)).
