Transactions sorting by the original order too

This simple change is sorting the transactions by the order they were written in the file. So if you have sth like:

    ## Retreive all Machines [GET]
    + Response 200 (application/json)

    ## Delete Machine [DELETE]
    + Response 204
    ....
    ## Retreive all Posts [GET]
    + Response 200 (application/json)

    ## Delete Post [DELETE]
    + Response 204


Transactions will run in the order: GET all Machines, GET all Posts, DELETE Machine, DELETE Post.
