"""The command to create a cycle tweak.
A cycle tweak is a tweak that cycles to the parent position but doesn't
create a cycle of dependency. This type of tweaks
are very useful to create facial tweakers.
Args:
name (string): Name for the cycle tweak
edgePair (list): List of edge pair to attach the cycle tweak
mirrorAxis (bool): If true, will mirror the x axis behaviour.
baseMesh (Mesh): The base mesh for the cycle tweak.
rotMesh (Mesh): The mesh that will support the rotation transformations
for the cycle tweak
transMesh (Mesh): The mesh that will support the translation and scale
transformations for the cycle tweak
setupParent (dagNode): The parent for the setup objects
ctlParent (dagNode): The parent for the control objects
jntOrg (None or dagNode, optional): The parent for the joints
grp (None or set, optional): The set to add the controls
iconType (str, optional): The controls shape
size (float, optional): The control size
color (int, optional): The control color
ro (TYPE, optional): The control shape rotation offset
Returns:
multi: the tweak control and the list of related joints.
