PureScript Erlang hello world

• purerl fork of the PureScript compiler, available on the PATH as purs
• psc-package - standard version, using the purerl package set

Build: run psc-package build, or if installed, pulp build, or:

make

If you don't have purs on your path, or in particular if it's a mainline compiler version, you'll either need to run those commands with a temporary addition to the PATH (both psc-package and pulp look there for purs), or you may find a Makefile with specific path useful.

Run:

make run
