Investigate using FunFlow to cache model simulation results

Possible hash method for matlab files: 

File-based

1. Write each struct to a file named with a random UUID 
2. Make sure it is written to memory (Haskell library) for improved speed (ramfs)
3. checksum or hash file 
4. delete file

Other Appends:

• git hash of relevant repositories
• whether said repositories are dirty
• if dirty, hash the output of git diff or similar
• nix commit
• other deps or data?
  But how does FunFlow store binary data (i.e. data for abstract types)?
