Rename myelin output metrics

Currently, for get_axon_morphometrics there are:

• myelin_diam --> outer diameter of myelinated axon (axon + myelin)
• myelin_area --> surface of axon + myelin See lines in code.

this is not intuitive. The suggestion is to replace with:

• myelin_thickness --> outer equivalent circle minus inner equivalent circle [in mm]
• myelin_area --> surface of {axon + myelin} minus surface of {axon}

Sure, that’s how it has always been

Was the g-ratio divided by the myelin area (name of the variable) or by what it represented (the area of the myelined axon)? I chose the former case, but apparently it should be the latter.

@maf88 originally, myelin_area (the variable and the stats output) was axon+myelin (as you probably figured out from the code). Hence, the gratio was correctly defined.

i agree this is confusing: this is precisely the purpose of this issue 😉
