Creates a sudoku board using dynamically created array of arrays. Each
array in the big array will have a character in it, either a number
or an underscore(representing unassigned). The sudoku board will be
able to place characters at each location, get the character at a location,
remove a character at a location, check if a character can be placed at
a location, print the board, and check if the sudoku board is solved.
