cocopp.readalign.MultiReader(list) class documentation

List of data arrays to be aligned.

The main purpose of this class is to be used as a single container
of the data arrays to be aligned by :py:meth:`alignData()` in the
parent module.
A data array is defined as an array where rows correspond to
recordings at different moments of an experiment. Elements of these
rows correspond to different measures.
These data arrays can be aligned along the time or the function
values for instance.

This class is part abstract. Some methods have to be defined by
inheriting classes depending on wanted alignment:

  * :py:meth:`isFinished()`, True when all the data is read.
  * :py:meth:`getInitialValue()`, returns the initial alignment
    value.
  * :py:meth:`newCurrentValue()`, returns the next alignment value.
  * :py:meth:`align()`, process all the elements of self to make
    them aligned.

Some attributes have to be defined as well :py:attr:`idx`,
the index of the column with alignment values in the data array,
:py:attr:`idxData`, the index of the column with the actual data.
