Interface for CS345 Pente Game's model

README.md

What Gollum-in-the-closet responds to (without screaming)

• Is ___ a legal place to move? / Is ___ a legal move? (yes/no)
• Place ___'s stone at ___ / Make move ____
• // How many stones has player ___ captured? (0 through 10)
• Who has won the game? (White/Black/Nobody yet)
• Whose turn is it? (White/Black)
• What piece is at location _____? (White/Black/Empty)
• How wide is the board?

Low priority:

• Max adjacent stones of stone ___? (0-4) [For user-assistance coloring purposes, still allowing sneaky XX-XX wins.]
• Is player ___ one stone away from winning?
