Title: Issue233

According to the comments associated with issue #233, the KSpace is stored in GridCurve as a pointer.
Moreover, models of CCellularGridSpaceND, like this KSpace, are made default-constructible, so that GridCurve can remain default-constructible.
Further changes will be made soon to improve the internal storage: storing only one kind of scells (of dimension 1 or d-1) instead of two (of dimension 0 and 1 respectively)
