/*
	LayedDataStructure WorstMatrix: Simple matrix using the regular array from javascript, may store either integers or booleans.
	
	-type: the type of data it stores (integers or booleans)
	-matrix: javascript array for storing the states
	-topology: Layer's edge rule ('noloop','xloop','yloop','xyloop')
   -dimensions: the size of the LayerDataStructure
	
	specs: {
		dimensions,
		type,
		topology,
	}
	
	+getCell(coords): returns the state of the cell given by the coordinate parameter
	
	+setCell(coords, value): set the state of the cell given by the coordinate parameter to the given value, returns true if successful
