Uninvert phrase around commas

• Short Description: Uninvert the input phrase around commas.
  
  
• Full Description:

  Controlled vocabularies sometimes invert terms, so that the important part of the term, the head, is at the beginning of the term. For example, the term "Percutaneous Coronary Transluminal Angioplasty" could be inverted to be "Angioplasty, Transluminal, Percutaneous Coronary". This flow undoes this inversion.

  No effect on the -m option. "none" is added at the end of the output.

• Features:
