- Added new `cable` composite type: * The `initial` parameter specifies the joint at the starting boundary: `free`, `ball`, or `none`. * The boundary bodies are exposed with the names:`B_left` and `B_right`. * The vertex initial positions can be specified directly in the XML with the parameter `vertex`. * The orientation of the body frame **is** the orientation of the material frame of the curve. - Added new `cable` passive force plugin: * Twist and bending stiffness can be set separately with the parameters `twist` and `bend`. * The stress-free configuration can be set to be the initial one or flat with the flag `flat`. * New cable example showing the formation of plectoneme. * New coil example. * New belt example showing interaction between twist and anisotropy. * Added test using cantilever exact solution.
