/*
 *  call-seq:
 *     TypedRangeQuery.new(field, options = {}) -> range_query
 *
 *  Create a new TypedRangeQuery on field +field+. This differs from the
 *  standard RangeQuery in that it allows range queries with unpadded numbers,
 *  both positive and negative, integer and float. You can even use
 *  hexadecimal numbers. However it could be a lot slower than the standard
 *  RangeQuery on large indexes.
 *
 *  There are two ways to build a range query. With the old-style options;
 *  +:lower+, +:upper+, +:include_lower+ and +:include_upper+ or the new style
 *  options; +:<+, +:<=+, +:>+ and +:>=+. The options' names should speak for
 *  themselves.  In the old-style options, limits are inclusive by default.
 *
 *  == Examples
 *
 *    q = TypedRangeQuery.new(:date, :lower => "0.1", :include_lower => false)
 *    # is equivalent to
 *    q = TypedRangeQuery.new(:date, :< => "0.1")
 *    # is equivalent to
 *    q = TypedRangeQuery.new(:date, :lower_exclusive => "0.1")
 *
 *    # Note that you numbers can be strings or actual numbers
 *    q = TypedRangeQuery.new(:date, :lower => "-12.32", :upper => 0.21)
 *    # is equivalent to
 *    q = TypedRangeQuery.new(:date, :>= => "-12.32", :<= => 0.21)
