Emulating stata oneway and twoway function

[eloualiche]

The reference for stata

• oneway here
• twoway here

Some first things I could implement

• tabulate oneway
  • plot an histogram
  • tabulate with multiple variables
• tabulate twoway
  • Option to represent the twoway in a wide table rather than long table (current) default
