pwiz columns invalid names
Hmmm....
 Can you explain this in a bit more detail? What exactly is the nature of this bug?
 This is a example of generated code from pwiz

class Flag(BaseModel):
    description = TextField(null=True)
    flag id = CharField(null=True)
    name = CharField(null=True)

python will syntax error:

```
flag id = CharField(null=True)
      ^
```

SyntaxError: invalid syntax
 Solution could be to escape the fields name and use a db_column property

flag_id = CharField(db_column='flag id', null=True)

in mysql fields can be named:
"source id"
"marketing/position"
in this case pwiz creates python model attributes of the same name.
