Errors in example usage in querying/README.md

[fabianbauermarquart]

The line

success, r, t = q.solve(a < b, return_values=[i])

in querying/README.md contains an error.
TypeError: solve() missing 1 required positional argument: 'args'

It would make sense changing the example to

import dl2lib as dl2
import dl2lib.query as q
from configargparse import ArgumentParser

parser = ArgumentParser(description='DL2 Querying')
parser = dl2.add_default_parser_args(parser, query=True)
args = parser.parse_args() # additionaly arguments such as timeout etc.
NN = q.Model(myPytrochModel)
i = q.Variable('i', (10,))
a = i[0] + i[3]
b = NN(i[4])
success, r, t = q.solve(a < b, return_values=[I], args=args)
