Bugfixes

0.1.2

It is now possible to pass a Range as first argument to #where_assoc_count. Ex: Users that have between 10 and 20 posts User.where_assoc_count(10..20, :==, :posts) The operator in that case must be either :== or :!=. This will use BETWEEN and NOT BETWEEN. Ranges that exclude the last value, i.e. 5...10, are also supported, resulting in BETWEEN 5 and 9. Ranges with infinities are also supported.
