Formatting changes to make code easier to read.
Add tests for creating datadirs.
Renamed and cleaned up print statements plus changes for RContinue -> ROk
Change RContinue to ROk. Add RFatal
Add Parent and Acces to NewDataDir(). Add method for deleting entry.
Renamed
Use respOk. Now takes an argument.
Change RContinue -> ROk and corresponding method changes. Have respOk take
an argument. Have r.req() be used rather than decoding directly.
RContinue -> ROk
Use r.req() to get request rather than decoding ourselves. This consolidates the error checking
to one spot.
Fixes and changes as the unit tests are coded up and we test the various cases.
