K-Dimensional Tree [Delete]

If node to be deleted is a leaf node, simply delete it (Same as BST Delete)
If node to be deleted has right child as not NULL (Different from BST) 
Find minimum of current node’s dimension in right subtree.
Replace the node with above found minimum and recursively delete minimum in right subtree.
