Detailed Description
Initializes most variables in the Grid structure.
PURPOSE: Initializes most variables in the Grid structure. Allocates memory for 3D arrays of Cons, interface B, etc. With SMR, finds all overlaps between child and parent Grids, and initializes data needed for restriction flux-correction, and prolongation steps.

PRIVATE FUNCTION PROTOTYPES:
- checkOverlap() - checks for overlap of cubes, and returns overlap coords
- checkOverlapTouch() - same as above, but checks for overlap and/or touch

Function Documentation
Checks for overlap of cubes, and returns overlap coords.
Checks if two cubes are overlapping.
- If yes returns true and sides of overlap region in Cube3
- If no returns false and -1 in Cube3
Arguments are Side structures, containing indices of the 6 sides of cube
