FileTimestampDao

Writes stuff (T values) down under the given directory structures:

<dir>/dates/<date>/<hour>/<minute>/<second>_<nano>_<id> = *data*

where *data* is determined by the given Persist, which is either the data itself or a linked file.

The implicit Persist may only link to the former instead of serializing the data

T: the value to save/retrieve
rootDir: the directory under which all the data will be stored
saveValue: the Persist instance to use in saving (or linking) the data.
fromBytes: a means of deserializing a T from bytes
idFor: the ability to name the T values w/ an ID (as multiple Ts can exist for the same instant)

new FileTimestampDao(rootDir: Path)(implicit saveValue: Persist[T], fromBytes: FromBytes[T], idFor: HasId[T])

rootDir
the directory under which all the data will be stored
saveValue
the Persist instance to use in saving (or linking) the data.
fromBytes
a means of deserializing a T from bytes
idFor
the ability to name the T values w/ an ID (as multiple Ts can exist for the same instant)
