metrics-miscellany 0.3.3

Miscellaneous code for estimation involving pandas dataframes.

Code implementing various statistical and econometric tools, developed haphazardly.  Hence the "miscellany".

Key ideas that motivate this collection:
   1. Input and output dataframes or series, or (better!) DataMats and DataVecs from the [[https://github.com/ligon/DataMat][datamat]] project.
   2. Provide clear, clean, integrated tests of estimators.
   3. Adopt semantics similar to the mathematical description of the estimation or inference problem.
