// Class : AnimChannelMatrixDynamic
// Description : An animation channel that accepts a matrix each frame
// from some dynamic input provided by code.
//
// This object operates in two modes: in explicit mode,
// the programmer should call set_value() each frame to
// indicate the new value; in implicit mode, the
// programmer should call set_value_node() to indicate
// the node whose transform will be copied to the joint
// each frame.
