This pull request adds support for expanding environment variable expansion support. Closes #91 Since the user controls the call site of cmd-env, it only supports basic UNIX style $var format. `%var%` (windows) or `${var}` is not supported. However, you can escape variable expansion by escaping the dollar sign like so `\$`. Signed-off-by: omeid matten <public@omeid.me>
