cheetah output wrong

[tjlane]

should all be one file

[sellberg]

the output was fixed to one file including data arrays called 'x', 'y', and 'z', but the numerical format of the arrays are wrong and makes the cheetah to segmentation fault (most likely because the values are way too big and the internal arrays of the cheetah goes out of bounds when it interpolates), needs some more debugging of how pypad generates cheetah coordinates.. [should be in m, not mm!]

the bug has been fixed! c5b99fe
