Generate a Cost-Distance raster based on a set of starting points and a cost raster
Cost Tile (Int)
List of starting points as tuples
Operation will only work with integer typed Cost Tiles (BitCellType, ByteConstantNoDataCellType, ShortConstantNoDataCellType, IntConstantNoDataCellType). If a double typed Cost Tile (FloatConstantNoDataCellType, DoubleConstantNoDataCellType) is passed in, those costs will be rounded to their floor integer values.
