How to modify a Channel values
==============================

In this example we access the Channel numpy array to modify it.

Given a Channel named channel::

    array = channel.getNDArray()
    #modify it data
    array[::2,::2,::2] = 1
    #tell the channel that it data was modified (this can trigger event)
    channel.setDataDirty()
