---clean up
---implemented wk theorem in time only. This code is working.
---Time correlation now works. Produces a plot of tau v radius, and
outputs the average correlation time and it's standard deviation.
---clean up.
---change field from real to complex before using wk.
---minor fix
---change from png to jpg for films
---make perp output in SI. Temporarily remove time window since giving
crap.
---fixed graphs and output of perp fit values.
---made time correlation time windowed to attempt to track large scale
long-lived blob and exclude it from time correlation calculation
---minor fix
---test plotting
---minor
---If time corr is zero, try fitting only the central peak. Implement
time window for time correlation.
---corrected error of taking time windows AFTER changing to frequency
space
---Added axes labels
Merge branch 'master' into wk_time_only
---Merging branch into master as a replacement.
