Start of mapping values to the gird an labels

-Creation of cellHolder class. Will create an object which holds the
array of panels. Has methods to get the entire array and to return a
single pane. Move the entire cell array into cellHolder so it can be
accessed by all classes.

-Created method setSolutions in logicGUI. currently this will map values
to the labels panels. TODO: add a method in gridPanel to populate the
solutions for each grid. Will need to detect which grid it is by
checking the index of a panel in cellHolder.

-Started method solutionMap in gridPanel. This method will detect which
grid is being used, and pull the appropriate data, and set the
logicButton solution to true if coordinates match.

-logicButton class has been stripped and is now a single boolean value
for true or false
