Installation guide for IBM Rational Rhapsody 8.3.1

I've published my installation guide for IBM Rational Rhapsody 8.3.1 client.

This is provided as a pptx (because pictures paint a thousand words). As well as steps for installing it includes steps for checking that the Cygwin compiler is working, Rhapsody Gateway is installed and licensed, and that Webify is working.

Also included are:
- Downloading and installing a evaluation version of Rhapsody.
- How to obtain and install the 8.3.1 iFix 1 (for Jazz/am usage, aka Rhapsody Model Manager).
- Minimal choice for installing Cygwin gcc and make (unlike the Rhapsody help suggested choice).
- Installing SysMHelper sample profile (and advanced open source example of profile and for SysML / executable MBSE with an automotive slant).
- Tips on silent download.

The steps take the approach of installing all Editions and tailoring the rhapsody.ini afterwards (the approach most Rhapsody Application Engineers use).
