Preliminary support for accessing named events through a Transform method
Merge branch 'master' of https://github.com/biometrics/openbr into events
Traverse the transform tree using properties

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.
A little cleanup

Move implmeentation of getEvents to the .cpp file, make getChildren const and
public.
Merge pull request #70 from biometrics/events
