First commit:
When buid tree function call find_best_split, there is no sum of targets and number of targets in root node. Therefore, left_sum will be -right_sum and lcnt = -rcnt.
Second commit:
Only swapped variable "w" and "h" because w belongs to variable x and h belongs to variable y. Anyway, there is more places in the code where variable x indicates y-coordinate because in Menpo library, the first coordinate is y-coordinate not x.
