Description:
 def add_toolkit_dependency(topology, name, version):
 """Add a version dependency on an SPL toolkit to a topology. To specify a range of versions for the dependent toolkits, use brackets (``[]``) or parentheses. Use brackets to represent an inclusive range and parentheses to represent an exclusive range. The following examples describe how to specify a dependency on a range of toolkit versions: * ``[1.0.0, 2.0.0]`` represents a dependency on toolkit versions 1.0.0 - 2.0.0, both inclusive. * ``[1.0.0, 2.0.0)`` represents a dependency on toolkit versions 1.0.0 or later, but not including 2.0.0. * ``(1.0.0, 2.0.0]`` represents a dependency on toolkits versions later than 1.0.0 and less than or equal to 2.0.0. * ``(1.0.0, 2.0.0)`` represents a dependency on toolkit versions 1.0.0 - 2.0.0, both exclusive.

 Topology to include toolkit in. name(str):
 Toolkit name. version(str):
