A straightforward wrapper of common java.nio.file.* functionality. All functions
use the Pathish protocol to turn their arguments into Paths.

Support for using Clojure functions in Java APIs requiring
a SAM (Single Abstrace Method) interface.

Currently uses java.lang.invoke.MethodHandleProxies to
convert an method handle to a SAM type. The method handle
generated for the IFn will translate to something akin to
the below (using method handle notation for signatures):

(-> SAM call
    (Object...)Object[]
    RT.seq(Object[])ISeq
    IFN.applyTo(ISeq)Object)

This is not intended to be highly performant, but, as it
has not been benchmarked, may or may not be. It is mainly
intended to provide a more convenient interop with Java
APIs that take SAM arguments.

Wrapper API for the java.lang.invoke API. Primarily this was limited
to the methods functions needed to support ike.cljj.function.
