Combinations
------------

You can combine different transformations simply by successively applying them.

Here, we first force the single field realization to hold the given moments,
namely mean and variance.
Then we apply the Zinn & Harvey transformation to connect the low values.
Afterwards the field is transformed to a binary field and last but not least,
we transform it to log-values.

We can select the desired field by its name and we can define an output name
to store the field.

If you don't specify `field` and `store` everything happens inplace.

The resulting field could be interpreted as a transmissivity field, where
the values of low permeability are the ones being the most connected
and only two kinds of soil exist.

All stored fields can be accessed and plotted by name:
