Deletes a work type from the system. The underlying SQL includes a referential-integrity guard:
if the work type is still referenced by any existing workOrderEventTechnician entry, the delete will be prevented rather than silently orphaning records.

---
### Parameters
**workTypeId** `Integer`: Id of the work type to delete<br />
**userId** `Integer`:Id of the user executing the function<br />

---
### Returns
**# of records modified** `Integer`<br />
**message** `String` None if success<br />

---
### Example
```python
# Attempt to delete the "Design" work type
workTypeId = 4
userId = system.kanoa.security.getIDPUserId({"userName": 'SYSTEM'})
recordsModified, message = system.kanoa.cmms.deleteWorkType(workTypeId, userId)
print recordsModified, message
```
