Data.Frames in boost.uBLAS

To implement the dataframes library for uBLAS using Expression Templates and Meta-programming paradigm in C++ that is capable of doing simple manipulations with data sets. It requires studying the existing implementations (data.table/data.frame in R and Pandas in Python) and analyzing the limitations (that occur due to template meta-programming paradigm) and possible optimisations (instantiation of type parameters which is not possible in R and python because of generic implementation of data.frame).
