More things with grids!

Spatial

• Grids.getLine: get an array of cell positions that connect to points
• Grids.getVectorFromCardinal: get an x,y vector corresponding to a cardinal direction like ‘north east’.
• Grids.neighbourList: returns an array of cells around a cell
• Grids.offset: calculate position offset from a cell. Includes logic for wrapping around the boundaries of a cell.
• Grids.offsetCardinals: compute the location of cells in the cardinal directions from a target cell

Comparison

• Grids.cellEquals: compares equality of cell position
• Grids.inside: returns true if a cell position is within bounds of a grid
• Grids.isCell: returns true if the passed object seems to be a cell (ie it has x & y properties)
• Grids.isEqual: returns true if two Grids have same value

1D Indexing

• Grids.cellFromIndex: get the {x,y} from an index.
• Grids.indexFromCell: returns the index for a given cell position.
