 1 | JOGridView
 2 | ==========
 3 | 
 4 | This is a grid view based on the concepts that UITableView set forth to provide.
 5 | 
 6 | - A cell is one portion of a grid
 7 | - Cells are bare now, need more features to pack it.
 8 | - Cells are re-usable
 9 | - The grid is defined by rows and columns
10 | - Rows have individually settable heights
11 | - Column widths are limited to the equal distribution amongst all columns in a row
12 | - There is no selection at this moment.
13 | - It automatically purges reusable cells when there is a memory constrain
14 | 
15 | TODO:
16 | =====
17 | - clean up first before laying out to conserve on memory
18 | - consistent delegate/datasource method signatures
19 | - cellforrowatindexpath in JOGridView (wtf is it really for?)
20 | - reflow cells?
21 | - heightforrowatindexpath doesn't work before cache values are not done right when heightforrow is set dynamically (should cache using assoc storage)
