Implement a Vector class. It should take an undefenite amount of parameters and behave like this:
>>> v1 = Vector(5, 9, -8, 2, 13, -23, 0, 0, 12)
>>> v2 = Vector(6, 8)
>>> v3 = Vector(-1, 1, 1, -1)
>>> v4 = Vector(0, 0, 0)| # import config. | |

| cnf ?= config.env | |
| include $(cnf) | |
| export $(shell sed 's/=.*//' $(cnf)) | |
| # import deploy config | |
| # You can change the default deploy config with `make cnf="deploy_special.env" release` | |
| dpl ?= deploy.env | |
