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
