Cannot use vector-valued output of micro simulations in adaptivity

[mathiskelm]

With #142 the micro-manager aborts if a vector-valued output of the micro simulations is included in the adaptivity data.

I obtain the following error message:

TypeError: float() argument must be a string or a real number, not 'list'

The above exception was the direct cause of the following exception:
[...]

    self._data_for_adaptivity[name][i] = micro_sims_output[i][name]
ValueError: setting an array element with a sequence.
