Changes in version 0.1.0                        

  - A new package containing functions for implementing greedy
    algorithms for constructing maximal partial Room squares.
  - Functions for testing if squares are partial Room squares, Room
    squares or maximal partial Room squares.
  - Functions for calculating the volume of partial Room squares.
  - A Room R6 class provided as an alternative interface for algorithm
    implementation.
  - Some convenient combinatorial functions for constructing sets of
    pairs.
