Initial noodling and tests for datalib and interface objects
Datalib#datasets returns array of symbols representing datasets in library
Bang version of build to support overwriting an existing dataset.
Unknown datasets return nil instead of raising an error.
CanonicalDatalib documentation
Basic row and row set classes.
Simple by group works, spec needs cleanup
Missed committing row and row set specs.
Removed overly complex spec
Documentation of RowSet class.
eof -> last_row
Reader/writer for canonical interface with spec.
Datalib as a delegator.
Refactored CanonicalDatalib to give the same dataset objects whenever accessed.
Datalib documentation
Refactored VariableSets#var to be more natural
Moved all of my deprecated specs so I can easily test the new ones.
Refactoring of VariableSet to make definitions simpler
Update variable spec to conform to Rspec 3.x standards.
