Documenting Creation of sets theory

0. [not related to theory creation, could skip to next step] Start afresh, create a branch

 mkdir kbansal.CVC4.set; cd kbansal.CVC4.set
 git clone https://github.com/kbansal/CVC4 ./
 git branch sets
 git checkout sets
 # usual configure, build etc.
 ./autogen.sh
 ./contrib/get-antlr-3.4
 <run configure command as given by previous script>

1. Creating basic infrastructural files. Use the contrib/new-theory script:

 ./contrib/new-theory sets
 # Previous command calls autogen, but still need to call:
 ./configure     #with any other options, like for specifying antlr
 make

For the record, this was the output of new-theory script (which tells what all it did)
