New workbook explaning Status of transaction Receipt

[juanfranblanco]

A workbook explanaing the Status of transaction, failed or passed.

Examples of unit tests below.

Thanks for note on Parity configuration: "eip658Transition": 0. It took a time fo me to understand why test chains do not provide correct Status value.
