produced axons are not symmetric

def __create_ref_nodes(self):

This function doesn't make symmetric axons, although centered.

Symmetric exmaple
o--x-x------x------x-x--o-x-x------x------x-x--o

Asymmetric example
o--x-x------x--------x--o--x-x------x--------x--o

This imposes directionality in the VTA from an array.

Example

from Axon_files.axon import *
a = Axon({})             # the default centered axon

# according to McIntyre each internode must be comprised of 
# MYSA -- FLUT -- 6x STIN -- FLUE -- MYSA
# sandwiched by Ranvier nodes. The default reference axon
# has 20 compartments each with 10 internodal segments. 

ref_nodes = a._Axon__create_ref_nodes() # shape: 221

inter1 = ref[1:11]      # location of the 10 segments of first internodal compartment
# inter2 = ref[12:22] # location of the 10 segments of second internodal compartment
#  ...

# if the internodal segments are symmetric, then their
#  location difference too must be symmetric
np.diff(inter1)  # it's not!
