>> lasview lidar.las
>> lasview -i lidar.las

reads around 500000 subsampled lidar points and displays in 100 steps

>> lasview -i lidar.las -win 1600 1200

same as above but with a larger display window

>> lasview -i lidar.las -steps 10 -points 200000

reads around 200000 subsampled lidar points and displays in 10 steps
