class_docstr: Class for fitting the Diffusion Kurtosis Microstructural Model 
class_docstr_tok: ["Class","for","fitting","the","Diffusion","Kurtosis","Microstructural","Model"]
docstr: Returns the volume fraction of the restricted diffusion compartment
  also known as axonal water fraction.
  
  Notes
  -----
  The volume fraction of the restricted diffusion compartment can be seem
  as the volume fraction of the intra-cellular compartment [1]_.
