Short intro: added technical introduction

Until now, there was no technical introduction (on what is the
necessity of Maneage in relation to Jupyter, Conda and Docker)!

While preparing the slides for the ESO "Reproducibility and Open
Science in Astronomy" meeting, I thought it will be helpful to add
such a comparison.

-
-    Maneage and its principles are described in \textcolor{blue}{\href{https://arxiv.org/abs/2006.03018}{arXiv:2006.03018}}.
-    It is a customizable template that will do the following steps/instructions (all in simple plain text files).
+    Maneage (\textcolor{blue}{\url{https://maneage.org}}) is a customizable template that will for research or data reduction:
     \begin{itemize}
-      \item \alert{Automatically downloads} the necessary
-        \emph{software} and \emph{data}.
-      \item \alert{Builds} the software in a \alert{closed
-        environment}.
-      \item Runs the software on data to \alert{generate} the final
-        \alert{research results}.
-      \item Modification of part of the analysis will only
-        result in re-doing that part, not the whole project.
-      \item Using LaTeX macros, paper's figures, tables and numbers
-        will be \alert{Automatically updated} after a change in
-        analysis. Allowing the scientist to focus on the scientific
-        interpretation.
-      \item The whole project is under \alert{version control} (Git)
-        to allow easy reversion to a previous state. This
-        \alert{encourages tests/experimentation} in the analysis.
-      \item The \alert{Git commit hash} of the project source, is
-        \alert{printed} in the published paper and \alert{saved on
-          output} data products.  Ensuring the
-        integrity/reproducibility of the result.
