Get sqltyped up to date with Scala 2.11

[vdichev]

I know you've mentioned that you're not maintaining sqltyped right now, but I'd like to see it live on, as it has some features that I don't see with the alternatives:

• like you said, Slick has a typed sql feature, but I do not like the fact that it infers the types only and doesn't take column names into account. With many columns with the same type and with typos in long column names this doesn't help too much.
• doobie has an interesting approach (https://tpolecat.github.io/doobie-0.2.3/06-Checking.html) where one can check the query at runtime but without the need to actually run it. This makes it an acceptable alternative to typed queries. However, even though doobie works with records, it discards the column names (Record names not checked with column names typelevel/doobie#277) and uses positions only, which is counterintuitive after having seen sqltyped. This also makes using records seem unnecessarily difficult since unlike sqltyped they are constructed manually.

Regarding compilation speed, it's true that shapeless does impose a tax on compile times, but things seem to have improved in recent editions. I haven't actually checked to compare with older versions, but it seems the complexity of some operations has been optimized: milessabin/shapeless#50

I'd like to hear your thoughts on future development of sqltyped and whether you'd want or have the time to provide some a small piece of help once in a while:

• updating the public maven repo is still maintained by you- are you willing to publish stuff from new pull requests?
• providing some advice on some future features which are tied to some knowledge that you already have, like why sqltyped has chosen to choose a certain design and not another

Thanks in advance for any help you can offer!

Hi Vassil,

This PR looks good and it is great if there's still interest in keeping sqltyped up to date and develop it further!

I will update the Sonatype maven repos this week and help with design issues any time. I will also give you commit rights to this repo so you can push changes more easily.

Thanks a lot!

Released 0.4.1 to Sonatype now.

I'm quite not as proficient with Scala as I would like, but this is one of the most interesting SQL libraries I've yet seen. It seems quite light weight in use and I'm really looking forward to playing with it. From what I understand, it is just pure SQL which is type checked at compile time and also returns typed values (in a nice type safe package with columns as class members).
My plan would be to add a sort of record layer Sqltyped. Be able to write something like:
sqlr"select [Person.*] from [Person]" - meaning that it would look at the companion object Person to determine the actual SQL table name and it's fields and return a list of Person. It'd be a way for me to easily add metadata to records which could be used and reused in UIs.
