v0.0.2

#3: Added two new modules:

1. operating-system: This can be used to detect the operating system on which Terraform is currently running.

2. join-path: This can be used to join multiple path parts (folders, files) into a single path, using the proper separator for the current OS.

The primary use case is so we can format paths properly on Windows vs Linux.

v0.0.1

#1: First release! We've created an intermediate-variable module.
