Functionality
-------------

This node generates a mask list ([True, False,..]) based on a index list (the True values) and a length or data-set

Inputs
------

* **Index**: Index of the True values
* **Mask Length**: Length of the mask list
* **data to mask**: when **data masking** is enabled the node will take the shape of the input data

Parameters
----------

* **data masking**: When enabled the length of the mask will be taken from the **data to mask** input.
* **Topo mask**: When enabled the mask will taken from the **data to mask** input but one level above, this is handy to mask vector lists or edge/polygon lists

Outputs
-------

* **Mask:** Mask List
