  """COCOeval wrapper class.

  Rewritten based on cocoapi: (pycocotools/cocoeval.py)
  Delta to the standard cocoapi:
    Detections that hit the 'seen' class objects are ignored in top-K proposals.

  This class wraps COCOEVAL API object, which provides the following additional
  functionalities:
    1. Include ignore-class split (e.g., 'voc' or 'nonvoc').
    2. Do not count (or ignore) box proposals hitting ignore-class when
       evaluating Average Recall at top-K proposals.
