I love you Christopher
I have edited the step analysis. Now we look for a top and then search
on for a bottom. Once this is done, we carry on from the bottom and look
for a new top. We also filter out any steps that are smaller than our
lowest expected, and then output the data points between which we got
the mini step. 

Must add the directory too so we know which file set to look at...?
realised i wasnt setting my initial for loop index to carry on from the
bottom value index value.
Changes we made in lab today
