Extract the values of decision variables from a solution generated using the
*CBC* (COIN-OR branch and cut)
solver (via `cbc_solve`

).

`column_solution(result)`

- result
*CBC*result (`rcbc_milp_result`

) object.

`numeric`

values of the decision variables
in the solution (same order as columns in the constraint matrix used
to formulate the problem).

```
# \dontrun{
# Define optimization problem
## max 1 * x + 2 * y
## s.t.
## x + y <= 1
## x, y integer
# Generate solution
A <- matrix(c(1, 1), ncol = 2, nrow = 1)
result <- cbc_solve(
obj = c(1, 2),
mat = A,
is_integer = c(TRUE, TRUE),
row_lb = c(-Inf),
row_ub = c(1),
max = TRUE)
# Extract column solution
column_solution(result)
#> [1] 0 1
# }
```
