findNeighbor function problem

[yeseuleee]

findNeighbor function don't check that root_ variable is valid.(the func have not check if(root_ == 0) condition)
But radiusNeighbor function check that root_ variable is valid.
So if root_ is not initialized situation, findNeighbor make program fault and radiusNeighbor doesn't make fault.
Then I think should be add "check root_ code" in findNeighbor.
The code is important in dynamic cloud situation.
Then user can well know error situation.

For example,

template <typename PointT, typename ContainerT>
template
int32_t Octree<PointT, ContainerT>::findNeighbor(const PointT& query, float minDistance) const
{
if(root_==0) return -999;//****return error code that user defined
float maxDistance = std::numeric_limits::infinity();
int32_t resultIndex = -1;
findNeighbor(root_, query, minDistance, maxDistance, resultIndex);

return resultIndex;
}

Thanks for pointing this out. I added a check to the findNeighbor function. Now one has only to take care for return value -1.

Sorry for the delay. :/
