/** Bitmap functions.
  * Build a bitmap from integer array:
  * bitmapBuild: integer[] -> bitmap
  *
  * Convert bitmap to integer array:
  * bitmapToArray:    bitmap -> integer[]
  *
  * Return the smallest value in the set:
  * bitmapMin:    bitmap -> integer
  *
  * Return the greatest value in the set:
  * bitmapMax:    bitmap -> integer
  *
  * Return subset in specified range (not include the range_end):
  * bitmapSubsetInRange:    bitmap,integer,integer -> bitmap
  *
  * Return subset of the smallest `limit` values in set which is no smaller than `range_start`.
  * bitmapSubsetLimit:    bitmap,integer,integer -> bitmap
  *
  * Transform an array of values in a bitmap to another array of values, the result is a new bitmap.
  * bitmapTransform:    bitmap,integer[],integer[] -> bitmap
  *
  * Two bitmap and calculation:
  * bitmapAnd:    bitmap,bitmap -> bitmap
  *
  * Two bitmap or calculation:
  * bitmapOr:    bitmap,bitmap -> bitmap
  *
  * Two bitmap xor calculation:
  * bitmapXor:    bitmap,bitmap -> bitmap
  *
  * Two bitmap andnot calculation:
  * bitmapAndnot:    bitmap,bitmap -> bitmap
  *
  * Return bitmap cardinality:
  * bitmapCardinality:    bitmap -> integer
  *
  * Two bitmap and calculation, return cardinality:
  * bitmapAndCardinality:    bitmap,bitmap -> integer
  *
  * Two bitmap or calculation, return cardinality:
  * bitmapOrCardinality:    bitmap,bitmap -> integer
  *
  * Two bitmap xor calculation, return cardinality:
  * bitmapXorCardinality:    bitmap,bitmap -> integer
  *
  * Two bitmap andnot calculation, return cardinality:
  * bitmapAndnotCardinality: bitmap,bitmap -> integer
  *
  * Determine if a bitmap contains the given integer:
  * bitmapContains: bitmap,integer -> bool
  *
  * Judge if a bitmap is superset of the another one:
  * bitmapHasAll: bitmap,bitmap -> bool
  *
  * Judge if the intersection of two bitmap is nonempty:
  * bitmapHasAny: bitmap,bitmap -> bool
