""" Main image analysis
Gets user image analysis settings from the .csv file.
If multiple experiments have been selected by the user
(multi) each subfolder will be looped through. A nested
loop will then interate through each .tif image and
analyse. A .csv file will be produced for each folder
analysed with the name of each image and its % neurite
density and % myelination. A summary csv file will also
be produced with the average % neurite density and %
myelination for each subfolder. If statistical analysis
has been selected (stats) then MyelinJ's Rscript will be
run via the command line. If multple experiments is not
selected then all of the images within the selected
folder will be analysed together and no summary .csv will
be produced.
Independ of the analysis settings defined, a processed
myelin channel image and a processed neurite channel
image will be saved. The images can be any number of
subdirectories (folders within folders).
Parameters
----------
cwd : string
Path for current working directory (location of
MyelinJ folder in Fiji).

stats: boolean

experiments: 2D list of strings
list of all the subfolders (experiments) that are in each
experimental condition.
multi: boolean
Analyse multiple experiments?
Rloc2: string
file path to Rscript location
subfoldernames: string
name of each subfolder which denoates each individual
experiment, if multple experiments are being analysed.
names: array
array of textfields for each experimental condition defined by
