Create hivememo file from plain text

Fast way to create a hivememo file from your existing files.

An entry is started with #, front and back are separated by ---, and pages are separated by ###. Example:

  # What is life?
  --- 
  Life is the aspect of existence that processes, acts, reacts, 
  evaluates, and evolves through growth (reproduction and metabolism).

  ###  
  
  # Forgetting curve
  ---
  This curve shows how information is lost over time 
  when there is no attempt to retain it.

Keep less than 150 entries per page to have enough playground.
