Create a Honeybee Model, which can be sent for simulation.

### Inputs

* **rooms**

A list of honeybee Rooms to be added to the Model. Note that at least one Room is necessary to make a simulate-able energy model.

* **faces**

A list of honeybee Faces to be added to the Model. Note that faces without a parent Room are not allowed for energy models.

* **shades**

A list of honeybee Shades or ShadeMeshes to be added to the Model.

* **apertures**

A list of honeybee Apertures to be added to the Model. Note that apertures without a parent Face are not allowed for energy models.

* **doors**

A list of honeybee Doors to be added to the Model. Note that doors without a parent Face are not allowed for energy models.

* **name**

Text to be used for the Model name and to be incorporated into a unique model identifier. If no name is provided, it will be "unnamed" and a unique model identifier will be auto-generated.

### Outputs

* **report**

Reports, errors, warnings, etc.

* **model**

A Honeybee Model object possessing all of the input geometry objects.
