Why is Condition a metaclass?

[sbellem]

On a related note, why not provide an __init__ to Condition?

Such that instead of the following

condition = Condition()
condition.type_id = type_id
condition.bitmask = bitmask
condition.hash = _hash
condition.max_fulfillment_length = max_fulfillment_length

we could simply do:

condition = Condition(
    type_id=self.type_id,
    bitmask=self.bitmask,
    hash=_hash,
    max_fulfillment_length=max_fulfillment_length,
)

[diminator]

Condition is an abstract class and should only be initialized by it's children (practically)

I think the example might be misleading... we could change it
