Progress towards stitching a map

- Add gridHeight and gridWidth properties
- Fix the ability of overriding keypress delays
- Fixed/edited debug messages
- Still not sure about map size estimation formula
- Added addToCanvas for created a stitched map
- Create the veritcal part of the loop for stitching together maps
