DataView should check the dimensionality of offset and count about nix HOT 3 CLOSED

I think that is implicitly done (DataView.hpp):

if (this->offset + this->count > array.dataExtent()) {
    throw OutOfBounds("Trying to create DataView which is out of bounds");
}

Because comparing the NDSize (offset + count) with dataExtent() will check the dimensionality:

template<typename T>
inline bool NDSize::operator<(const NDSizeBase<T> &lhs, const NDSizeBase<T> &rhs)
{
    if (lhs.size() != rhs.size()) {
        throw IncompatibleDimensions("size must agree to compare",
                                     "NDSizeBase < NDSizeBase ");
    }

from nix.

You're right. Didn't think to check that.
Would you like to add an explicit check? If you think the check in the comparison is enough, just close the issue.

I think that would be better, yeah, an IncompatibleDimensions with a more specific error message.
