Citcom SVE Proof of Concept

The first stage of our attempt to couple Citcom SVE3 and CISM using the CESM/ESMF coupling tools involves building a wrapper or interface code. This code will build Citcom SVE3 and CIME in the case control system. Our first test should be a simple set-up of Citcom SVE3 only, to prove that we can build the necessary interface. This repository will include all of the interface code for Citcom SVE3, plus documentation and testing. The tasks required to reach this proof of concept include...

Tasks for Citcom only:
- [ ] Build standalone on Derecho and document process
- [x] Get LGPTL license set up
- [x] Create github repository for code source control
- [ ] Choose the test case
- [ ] Get needed input data on Derecho and available

Tasks for Interface code:
- [x] Create repository for the interface
- [x] Add git-fleximod and set up submodule framework
- [x] Add submodules for CIME and Citcom SVE
- [x] Compset definitions
- [ ] Build with CESM (Fortran/C interfaces)
- [ ] Outline NUOPC files (init, run, finalize)
- [ ] Pass in first fields
- [ ] Recreate a known test case within the CESM framework and verify that we get the same answer
