circular-append-file

A simple appendable-file interface which enforces a size cap by overwriting itself.
A good way to maintain a log where you want to drop history after you hit a size limit.

Currently clears the file on open, then will write each append to the end until the maxSize is hit.
Will then circle back to the top and continue writing.

Currently only supports strings.

``js
const CircularAppendFile = require('circular-append-file')

let log = CircularAppendFile('./app.log', {
maxSize: 1024 // 1kb (default is 32mb)
})
log.append('Hello\n')
log.append('World!\n')
log.createReadStream().pipe(process.stdout)
log.close()
