Refactor the Puzzle Class And Cell And Group Class

puzzle will hold the master list , 

groups will hold a list of id's 

cells will hold a value 

The Finders will all directly work with puzzle and master list 

This should help allievate some of the current source of truth woes 

classes 
    Cell 
        value
    Group
        Members
    Puzzle
        Rows
        Columns
        Groups
        MasterList
        Finders
    Finders -> Finder
        FilterPossible()




find all available in a grid ,

then for each possible value left in grid 

figure out what cell can hold that value

if only on cell can hold that value assign that cell the value 


puzzle for each group
    neededValues = []
    candidates = {
        1 : [member]
        2
        3
        4
        ...
    }
    group for each member 
        add member potentials to needed neededValues
    neededValues for each value
        group for each member 
            if(member potential has neededValue)
                counter + 1
