Creating measurement configurations
-----------------------------------

There are two possible ways to create measurement configurations. Common to
them is a `crtomo.configManager` instance. It can either be created directory,
or implicitely through the creation of a `crtomo.tdManager` instance. This
tutorial will create a stand-alone instance of the configManager, but for a
given tdMan-instance 'man', the config Manager can be found at `man.configs`.

Create the configManager: ::

    import crtomo.configManager as edfC
    configs = edfC.ConfigManager(nr_of_electrodes=48)

Configs can now be created using one of the following functions: ::

    configs.gen_dipole_dipole
    configs.gen_gradient
    configs.gen_reciprocals
    configs.gen_schlumberger
    configs.gen_wenner

For the full documentation of these function, please refer to the code
documentation of each of them.

A few examples: ::

    configs.gen_dipole_dipole(skipc=2)
    configs.gen_gradient(skip=10, vskip=0)

The configurations are returned by the functions as a Nx4 numpy array, but are
also directly added to the internal configuration array, which can be accessed
as: ::

    configs.configs

.. todo::

    Explain the additional configuration functions, e.g., reciprocals, etc.

    Explain how to plot pseudosections

There are various ways to save the configurations into a file:

A four-column file is written using: ::

    configs.write_configs('configs.dat')

A CRMod config.dat file is written using: ::

    configs.write_crmod_config('config.dat')

A CRMod volt.dat file is written using: ::

    configs.write_crmod_config('config.dat', mid)

Here, mid refers to the measurement-id for a given measurement.
