Feature: Display size of resulting grid boxes

[thomas-shares]

Hi,
I think it would be really useful to display the size of the resulting boxes. If I am making parking spaces and I can't exactly count the number of spaces from the aerial data it would help if the height x width of the resulting box would be displayed. This give me another bit of information in sizing the boxes correctly (as most parking spaces are about 2 meters wide and about 5 long.

ps. and thank you for this great tool!!! very handy indeed for parking spaces.
