1. An instrument for angular and displacement control, comprising:
a pair of pivotally-connected arms, extending beyond a pivot axis of a first pivot;
a pair of feet having a relative displacement controlled by the pair of pivotally-connected arms, at least one foot being pivotally mounted for angular displacement with respect to the pivot axis;
an adjustment configured to control the angular displacement of the at least one foot with respect to the pivot axis; and
a mechanism, configured to maintain the relative angle of the pair of feet independent of the relative displacement of the pair of feet controlled by the pair of pivotally-connected arms, comprising at least one quadrilateral linkage, having a linkage constraining relative angles of the pair of feet, comprising the first pivot and at least a portion of each of the pivotally-connected arms.
