YDK for XML Serialize/Deserialize

Able to get YDK-gen to build my SDK based on YANG models.  Doing a simple test and just want YDK to spit out the XML.  This gives tracebacks... 

from ydk.models.cisco_customer import Data

from ydk.services import CodecService

from ydk.providers import NetconfServiceProvider 

myservice = CodecService()

myprovider = NetconfServiceProvider() 

foo = Data()

cust = foo.Customer()

cust.name = "Bill" 

print(myservice.encode(myprovider, foo))

Have added support for python3, which initially introduced a dependency on the future package. We are currently working to remove this dependency, but for the time being, please install the future package https://pypi.python.org/pypi/future.
