Refactored some code. Doing one get for method and type instead of metric ton.
Added ActivityState field to TaskData. This represents if the task is active or inactive. When active it will be taken to account in the optimization and if inactive optimization will not touch it.
Updated VehicleDataSet version number and changed vehiclesetimportrequests mimetype.
Using the taskset mimetype in import instead of task.
Added initialize method to testhelper. This will remove ALL users from the client before creating one user. This way there is only one user created at any single time.
