Octave function riGetWellCell index reference starting point

[hhgs]

The Octave function riGetWellCell index reference starting point should be (1,1,1) for I/J/K and 1 for BranchId and SegmentId and not 0 to be consistent with simulation input.

---

Vector[WellCellInfo] riGetWellCells([CaseId], WellName, TimeStep)
This function returns the cells defined in the specified well for the time step requested as a vector of Structures. The Structure is defined as:
WellCellInfo {
I, J, K = int # Index to the cell in the grid
GridIndex = int # the index of the grid. Main grid has index 0.
CellStatus = int # is either 0 or 1, meaning the cell is closed or open respectively
BranchId = int # Branch id of the branch intersecting the cell
SegmentId = int # Branch segment id of the branch intersecting the cell
