Not all use cases need the enumeration here. Allowing the enumeration to be deferred here allows for chaining of expression tree projection (i.e. DTO layer -> Entity layer -> SQL layer (via EF)). This is a really cool use case for this, but also means client programmers may get a couple bugs if they previously map to an ienumerable and rely on the automapper's enumeration call. Closes #184
