improve documentation

Matthieu correctly points out the documentation was a little sparse.
Add information about what one does after installing the repo: kind of a
spack crash course.

## Mochi Suite Installation
To build the entire mochi suite with the default configuration (mercury using
CCI's TCP transport), simply build margo:
spack install margo
### System boost vs. spack boost
The largest dependency for Mercury is the Boost package. If your system
already has Boost, you can teach spack about it and other
[system packages](
Let's say you installed Boost through your distribution (an RPM or DEB package)
To inform spack about Boost you e.g. installed from an RPM, you would add it to
boost@system: /usr
version: [system]
buildable: False
## Using Mochi Suite
One consequence of the spack design (where packages are installed into a prefix
based on a hash of their configuration and compiler) is that library and header
paths are unwieldy. An environment-managment tool such as `moudles` helps a
lot here, and is nicely integrated into spack:

Load the margo module into your environment:
module add margo-master-gcc-4.7.2-uy4in2w
The dependency resolution does not appear to be automatic (perhaps RobL needs
to adjust or declare runtime depenencies?), so you'll have to
add mercury, argobots, and abt-snoozer by hand as well.
