Add "static analysis" to todo list
:require matching ns when importing classes created by deftype

Classes created by deftype and defrecord are created on ns evaluation,
therefore that ns must be required before referencing these classes.

deftype and defrecord classes implement IType and IRecord in Clojure
1.3.0+, so we can check the hierarchy to identify them.

There is unfortunately no straightforward mapping of class package names
to Clojure namespaces as deftype uses clojure.core/namespace-munge to
simply change all \- to \_.

Therefore a two step search for the matching ns is made:

    1. Try the simple case where all underscores are converted to dashes
    2. Search for the first namespace that matches the package name with
       dashes and/or underscores.
