  This function queries a dictionary for a key. A key as read from an

  A true boolean is found if one of the following is matched:

  - A string starting with 'y'
  - A string starting with 'Y'
  - A string starting with 't'
  - A string starting with 'T'
  - A string starting with '1'

  A false boolean is found if one of the following is matched:

  - A string starting with 'n'
  - A string starting with 'N'
  - A string starting with 'f'
  - A string starting with 'F'
  - A string starting with '0'

  The notfound value returned if no boolean is identified, does not
  necessarily have to be 0 or 1.
