Something like this

Move implmeentation of getEvents to the .cpp file, make getChildren const and
public.

Look for properties with type Transform * or QList<Transform *> and for
getEvent, follow the tree using those, rather than having separate methods for
different transforms with children.

allow single template comparisons in PP5

Online distance metric added

Updated openTransform to not overwrite Templates with matrix data

If stream receives a templatelist with multiple templates, display them in
sequence (currently kind of a hack). If this behavior is undesirable, it can
be avoided by using distribute.

Fix a bug in FPSSynch, also rename it FPSLimit because it only reduces the max
frame rate of an algorithm, it doesn't do frame dropping or anything.
