0.15.0

Added

• Add Flop.reset_filters/1 and Flop.reset_order/1.
• Add Flop.current_order/2 to retrieve the order of a given field.
• Add Flop.to_next_page/2 and Flop.to_previous_page/1.
• Add Flop.set_cursor/2, Flop.to_next_cursor/1 and
  Flop.to_previous_cursor/1.
• Add Flop.set_offset/2, Flop.to_previous_offset/1, Flop.to_next_offset_2
  and Flop.reset_cursors/2.
• Add Flop.nest_filters/3 for converting filters between a key/value map and
  a list of Flop.Filter parameters.
• You can now set the default_pagination_type option, which forces a certain
  set of parameters when defaults are applied and the pagination type cannot
  be determined from the given parameters.
• Add optional default argument to get_option.
• Add pagination option. If set to true, pagination parameters are not cast.

Changed

• Flop.map_to_filter_params/2 returns maps with string keys if the original
  map has string keys now.
• The has_previous_page? value of the Flop.Meta struct is now always true
  if first is used with after. has_next_page? is always true when
  last is used with before.
• push_order/2 resets the :after and :before parameters now, since the
  cursors depend on the order.
• validate_and_run/3 and validate_and_run!/3 pass all given options to
  the validate functions now, allowing you to override defaults set in the
  schema.
• If the pagination_types option is used, parameters for other pagination
  types will not be cast now instead of casting them and returning validation
  errors.

Removed

• Remove Flop.Cursor.get_cursor_from_map/2. Use
  Flop.Cursor.get_cursor_from_node/2 instead.
