api/config/default.json does not work for local installation

[echism]

default.json includes this path

"upload": {
"path": "/opt/sca/data/uploads",
"host_path": "",
"max_file_size_bytes": 107374182400
}

/opt is protected and unwritable on Mac OS and this reference is probably not intended for local install anyway

[echism]

api will run if path is replaces with a writeable local directory
