Reduce dependency reliance for layers regarding data information

[hunkim98]

Currently each layer is a child of BaseLayer. The problem is that each child layer has its own column count, row count, topRowIndex, leftColumnIndex, which can be tricky to track its dependency on each other in future works. @Lee-Si-Yoon suggested that we either create diagram for this or control all the pertaining logic into one class.

I believe we have to make some modifications to DottngDataLayer to reduce such chaos.
