Added a clarificatory remark and one example to openReplicaSet'

Some new users might be put off by the lack of a array of choice between connection methods
that this package offers. This remark and the associated examples are a first attempt to make the package easier to start with.

# Resolver to choose a 'specific' stackage snapshot or a compiler version.
# A snapshot resolver dictates the compiler version and the set of packages
# to be used for project dependencies. For example:
#
# resolver: lts-3.5
# resolver: nightly-2015-09-21
# resolver: ghc-7.10.2

# The location of a snapshot can be provided as a file or url. Stack assumes
# a snapshot provided as a file might change, whereas a url resource does not.
