Added some additional documentation about installation.

life slightly easier, and in the future we hope to find a way to

bundle this installation into the Minke install script.

To install lalsuite and minke you should run::

  $ ./setup_environment.sh

in the root of the project, which will attempt to download and build the 

latest version of lalsuite, using the correct branch to run the minke code.

You can then install the Minke python package by running::

Installing in a virtual environment

===================================

We need to setup a virtual environment first. If you're using

virtualenvwrapper this is straightforward::

  $ mkvirtualenv <name for venv>

First install lalsuite from the minke branch on git::

  $ git clone https://github.com/lscsoft/lalsuite.git

  $ git checkout minke

  $ ./00boot

  $ configure --prefix=$VIRTUALENV

  $ make && make install

Then clone the minke repository, and install the code and dependencies::

  $ git clone https://daniel-williams@git.ligo.org/daniel-williams/minke.git

  $ pip install numpy scipy matplotlib pandas

  $ cd minke

  $ python setup.py install

=======================

System-wide installation

========================

We do not recommend system-wide installation of minke, however, it is possible.

First install lalsuite from the minke branch on git::

  $ git clone https://github.com/lscsoft/lalsuite.git

  $ git checkout minke

  $ ./00boot

  $ configure

  $ make

  $ sudo make install

Then clone the minke repository, and install the code::

  $ git clone https://daniel-williams@git.ligo.org/daniel-williams/minke.git

  $ sudo pip install numpy scipy matplotlib pandas

  $ cd minke

  $ sudo python setup.py install

Use on the LDG Clusters

=======================

Any code which is run in this virtual environment should link

automatically to the correct python packages to produce signals using

Minke.

Using Minke in docker

=====================

Minke is now available in a docker container, allowing you to run

Minke on any system which has docker installed. The container is

available on both dockerhub and git.ligo.org's registry.

To get the minke image from dockerhub just run::

  docker pull lpmn/minke

The process for fetching the image from gitlab is a little more

involved, as you need to be logged in to the registry first. ::

  docker login git.ligo.org

  docker pull git.ligo.org/registry/daniel.williams/minke
