Method	`__init__`	Example
Instance Variable	`grid`	Grid object
Method	`has`	Is coordinate (y,x) part of a span ?
Method	`reserve`	Store 2-tuples as coordinates to property _list, belonging to a span
Instance Variable	`_list`	List of 2-tuple cell coordinates (y,x) which are parts of any span

def __init__(self, grid=None):

Example

grid.spans = _Spans( grid )

Parameters grid required Grid object

grid =

Grid object

_list =

List of 2-tuple cell coordinates (y,x) which are parts of any span

(type: list)

def has(self, y=0, x=0):

Is coordinate (y,x) part of a span ?

if grid.spans.has( y=1, x=2 ) : pass
if grid.spans.has(1, 2)       : pass

def reserve(self, y=None, x=None, y_span=None, x_span=None):

Store 2-tuples as coordinates to property _list, belonging to a span

grid.spans.reserve( y=0, x=1, y_span=2, x_span=2 )
grid.spans.reserve(0,1, y_span=2, x_span=2)

Mark cells belonging to a span by adding tuples of (y,x) coordinates to property _list.
