The Python Script TOP can now be configured to evaluate its script code during the work item generation step instead of when the work items are cooking. That option is now available as one of three entries in a newly added "Evaluate Code During" parameter, which has replaced the In-Process toggle. It can be used to, for example, programmatically create attributes using PDG's Python API.

Added a hou.ik module with several functions and classes for inverse kinematics solvers. These provide access to the same solvers as the solvefbik() and solvephysfbik() VEX functions.
