Merge matrices horizontally  and vertically.

It is useful and important when we handle linear equations, statistics and so on.


```
Matrix[[1, 2], [3, 4]].row_merge(Matrix[[5], [6]])

  => 1 2 5
     3 4 6

Matrix[[1, 2], [3, 4]].column_merge(Matrix[[5, 6]])

  => 1 2
     3 4
     5 6

# accept more than two matrices as an argument.

Matrix[[1, 2], [3, 4]].column_merge(Matrix[[5, 6]], Matrix[[7, 8]])

  => 1 2
     3 4
     5 6
     7 8
```

* Matrix#row_merge needs Matrix#column
