Spatial Navigation should consider only those nodes as candidate which are
exactly in the focus-direction.
e.g. If we are moving down then the nodes that are above CURRENT focused node
should be considered as invalid.
Added isValidCandidate() which checks whether node is exactly in the
focus-direction,if it is not it start iteration
with next node and avoid extra calculation.
