Added `get_result` in Bliss Tango DS
I find very useful to add a get_result
command to the Tango Bliss DS, in order to retrieve the result of an executed command.
get_result
takes the cmd_id as parameter, and returns a base64-encoded pickle string. So only Python clients can decode it
at the moment... Maybe we could return some json instead... But it's less convenient for Python objects.
What do you think ?
