v1.4.9.0

v1.4.9.0

New features

1. add new cass P2Quantile that interfaces P^2 algortuhm from GSL for running quatile (approximate)
2. Add methods Ostap::Statvar::p2quantile, Ostap::StatVar::p2quantiles and Ostap::StatVar::p2interval. These are much faster (but approximate) versions of Ostap::StatVar::quantile, Ostap::StatVar::quantiles and Ostap::StatVar::interval, using P^2 algorithm.
3. update ostap.stat.statvar for modified Ostap::StatVar methods
4. allow uisng sqlite3 dbase for compresed shelves
5. extend compressed shelves to keep some metainformation on database (creating/modification date, versions of ostap, ROOT and python versions
6. add creation/modification date for the items in compressed shelves
7. add new test for splot test_fitting_splot

Backward incompatible changes

1. change return type from Ostap::StatVar::quantile , Ostap::StatVar::quantiles and Ostap::StatVar::intrval method, adding also number fo events used for quantile/interval estimation. It allows to judge abotu the precision

1. fix really stupid bug in ValueWithError
2. Tiny fix in Ostap.DataFrame.ProgressBar
3. fixed in_range option for the case when fit variables are defined as RooRealVar
