Fixes#105

Added a mutator function for the ViewField decorator which allows a reduce function to be set on a ViewField using a second decorator. This is just some sugar for creation a view with a map and reduce function using an explicit syntax.

Example

class Item(Document):     sku = TextField()     color = IntegerField()     stock = ViewField('people')     @stock.map     def map(doc):         yield doc['sku'], doc     @stock.reduce     def reduce(keys, values, rereduce):         if rereduce:             yield sum(values)         else:             yield len(values)

…ich allows a reduce function to be set on a ViewField using a second decorator.
