Overview

Provides behavior for mapping Ruby options to legacy OP_QUERY find modifiers.

This module is used in two ways:

When Collection#find is invoked with the legacy OP_QUERY syntax (:$query argument etc.), this module is used to map the legacy parameters into the Ruby options that normally are used by applications.
When sending a find operation using the OP_QUERY protocol, this module is used to map the Ruby find options to the modifiers in the wire protocol message.
