Performance

[jmboehm]

Many of the macros are generating code that is not type stable, and is therefore horrendously slow. This affects in particular

• egen/erep (fixed with first commit)
• generate/replace <-- should use Tables.namedtupeiterator and a barrier function
• reshape
  maybe more?

Merging this sooner rather than later. reshape_long is still painfully slow, which I think is coming from the fact that DataFrames.stack is slow (probably not type stable).

Some bug fixes too.

Also, this is changing the version to 0.0.1, in preparation for registration.
