Fast curves

A Fast curve is triggered by a certain event and then stores data for a certain period of
time than is then displayed in a curve window. The trigger event can be a digital signal
that goes high, an analog value reaching a limit value, or a manual triggering. The fast curve
can be configured to continuously store data so that also data before the trigger point can
be viewed.

A fast curve is configured with a DsFastCurve object. Up to 10 attributes can be handled by
one DsFastCurve object and the attributes are stated in the Attribute array. For each
attribute a buffer object should be created and stated in the Buffers array. Also a buffer
object for the time should be created and stated in the TimeBuffer attribute.
The size of the buffer objects should be adapted to the data quantity that is to be stored.

A fast curve can be viewed in the ordinary curve window, that is opened for example from the
Fast item in the popup menu. It can also be viewed in a Ge graph with a FastCurve component.
