feature 7

Save pictures
	done, pictures get saved in the same directory as the .py files

Save movement/head rotation commands
	gets logged in a .txt file

Log when what happened
	gets logged with the previous task in the .txt file

Measure height from ground to camera
	it seems like there is no way to do this with internal methods.
	- we can't know from which camera the picture is being taken.
	  solution: from experience we can assume it's always the top 		  camera, and measure the distance when the head is in the 		  "normal pose"

Calibration/measure movement noise
	working on it

Measure actual distance to landmarks every time a picture is made, for comparison to results from image processing to estimate measurement noise
	still need to measure this.
