## Description

Limit availability of plug-ins by host, such as Maya.

Integrations, such as `pyblish-maya` and `pyblish-nuke` register their own corresponding host automatically. Additional hosts may be registered by the end-user to customise the available plug-ins at time of publish.

## Example

```python
from pyblish import api

class CollectObjectSets(api.ContextPlugin):
    """Collect things only Maya would know"""
    order = api.CollectorOrder
    hosts = ["maya"]
    def process(self, context):
        from maya import cmds
        for objset in cmds.ls(type="objectSet"):
        context.create_instance(objset)
```
