App Catalog Conceptual overview

[Suresh Marru <sm...@apache.org>]

Hi All,

I am trying to describe app catalog from a high level conceptual perspective. A full E-R diagram explains in better, but I just want to provide a 5 minute overview of how Airavata manages applications without going into details. I tried to use this [1] paper as a reference to represent. 

I have started on a document describing the relations between various models, but since this is important enough for all of us to embrace, I want to try an experiment. Please look at the document [2] and reply back on what you are understanding. That way we had every one think through for a while, and I will keep answering questions/comments. Also critique as you go along. 

Can any one take a first stab at describing the figure at - https://cwiki.apache.org/confluence/display/AIRAVATA/Airavata+Application+Catalog
