This function is used when in direction a_dir a 3-point stencil of cell-centered data is being used to compute something at the center of the central cell of the stencil.
Inputs: a_dir is the direction of the 3-point stencil; a_inBox is the cell-centered box on which we are to compute a stencil (2-point or 3-point), expanded by 1 in a_dir direction, and not intersected with the domain; a_domain is the problem domain.
Output boxes are all cell-centered subboxes of a_inBox and are also contained in a_domain: a_loBox is where a 2-point stencil must be used on the low side; a_centerBox is where the full 3-point stencil can be used; a_hiBox is where a 2-point stencil must be used on the high side; a_entireBox is the union of a_loBox and a_centerBox and a_hiBox.
The boxes a_loBox and a_hiBox will be at most 1 cell wide; here the 2-point stencil consists of a cell from this box and the neighboring cell from a_centerBox in direction a_dir.
a_entireBox will be a_inBox with one layer of cells removed from both sides in dimension a_dir.
Output flags: a_hasLo: 1 or 0, according to whether a_loBox is defined or not; a_hasHi: 1 or 0, according to whether a_hiBox is defined or not.

This function is used when in direction a_dir a 2-point stencil of cell-centered data is being used to compute something at the face between cells of the stencil.
Inputs: a_dir is the direction of the 2-point stencil; a_inBox is the cell-centered box on which we have data; a_domain is the problem domain.
Output boxes are all face-centered subboxes of the faces of a_inBox in direction a_dir, and are also contained in the faces of a_domain: a_loBox is where a 1-point stencil must be used on the low side; a_centerBox is where the full 2-point stencil can be used; a_hiBox is where a 1-point stencil must be used on the high side; a_entireBox is the union of a_loBox and a_centerBox and a_hiBox.
The boxes a_loBox and a_hiBox will be at most 1 face wide; here the 1-point stencil consists of only 1 of the adjacent cells in direction a_dir.
Output flags: a_hasLo: 1 or 0, according to whether a_loBox is defined or not; a_hasHi: 1 or 0, according to whether a_hiBox is defined or not.

This function is used when in direction a_dir a 4-point stencil of cell-centered data is being used to compute something at the face between cells of the stencil.
Inputs: a_dir is the direction of the 4-point stencil; a_inBox is the cell-centered box on which we have data; a_domain is the problem domain.
Output boxes are all face-centered subboxes of the faces of a_inBox in direction a_dir, and are also contained in the faces of a_domain: a_loBox is where a stencil must be used on the low side with all four points higher; a_nextLoBox is where a stencil must be used on the low side with one point lower and three points higher; a_hiBox is where a stencil must be used on the high side with all four points lower; a_nextHiBox is where a stencil must be used on the high side with one point higher and three points lower; a_centerBox is union of a_innerCenterBox, a_nextLoBox, and a_nextHiBox, where the regular 2-point stencil can be used; a_innerCenterBox is where the regular 4-point stencil can be used; a_entireBox is the union of a_{lo|nextLo|center|hi|nextHi}Box.
Each of the boxes a_loBox, a_nextLoBox, a_hiBox, a_nextHiBox will be at most 1 face wide.
a_loBox and a_nextLoBox will both be defined or both be undefined. a_hiBox and a_nextHiBox will both be defined or both be undefined.
Output flags: a_hasLo: 1 or 0, according to whether a_loBox and a_nextLoBox are defined or not; a_hasHi: 1 or 0, according to whether a_hiBox and a_nextHiBox are defined or not.
