Documentation is lacking

[cgsmith]

It is very hard to figure out how to use the library without navigating to the classes to find out what each method is used. For example, to a novice, saving a file on the filesystem is not evident.

Some of the documentation isn't up to date, either. getRows is now getRecords, etc.
