Param usePrivateFiles in Builder.useSerializerInDisk() is missleading

[AlexTrotsenko]

Javadoc for usePrivateFiles params in Builder.useSerializerInDisk() says: "true if you want to use {@link Context#MODE_PRIVATE} with the default disk cache folder."

But, as far as I see, both folder below refers to the internal storage and Context.MODE_PRIVATE is used by default:

• context.getDir(CACHE_FILE_PREFIX + this.id, Context.MODE_PRIVATE)
• new File(context.getCacheDir().getPath() + "/" + CACHE_FILE_PREFIX + "/" + this.id)

So, the only difference is the path: later creates folder in the cache folder, which might be cleaned-up by the system.
