Request: change name of dir 'Tests' to 'Examples'

[wimrijnders]

The reason for this is:

• I believe the name is a misnomer, the directory contains example programs (perhaps excluding AutoTest).
• My intention is to add unit tests in due time, and putting it into any other directory than Tests will be confusing.

Please tell me if you agree to this change, I will make it myself.

Absolutely right, it should be Examples not Tests, except for AutoTest!
