Summary:  fixes #62 - readme updates

**Problem:**
Docs unexamined for a while

**Analysis:**
The opening line is cheesy, and there's nothing about the pipe-friendliness of the CLI tool, which is a really nice feature.
Remove that opener, and add info about the pipe-friendliness.

**Testing:**
None - doc issue only.

**Documentation:**
Updated the README.
