Installation instructions

[GoogleCodeExporter]

Steps to reproduce the problem:
1. Get to the main page of project
2. Try to understand what to do to start working with mockitopp

On the main page there should be "Installation" section, or link to this 
section in wiki. Preferrably installation should use some common tools (git + 
configure + make + make install?).

I've tried to use mockitopp and was unable to do it. It took me some time to 
understand that I should use `scons` to compile mockitopp and run tests. It was 
first `scons` project I've dealt with, so it is a bit unclear at first what to 
do with cloned repo.

Even after I run `scons` and all tests passed I didn't know what to do next. 
What should I do to use `mockitopp` in my unittests? With Boost or gtest or 
something else?

Maybe I overlooked something, in this case I apologise for newbish questions. 
But anyway I believe that installation section should be easily accessible to 
newcomers.
