Title: Added JRClj._lookup

If you want to use clojure.core/apply or clojure.core/swap! (with an atom), you need a var that references a function. You can create the var manually with

```ruby
require 'java'
java_import 'clojure.lang.RT'
RT.var namespace, fn_name
```

but jrclj has already done that for you. I've added a method _lookup that returns a var from the existing @mappings. If that is not a great function name, please rename to something more along the lines of your conception of the library.
