#BsplineQuantRegGui 0.2.2
### Fixes :
- update end knots multiplicities according to degree.
- temp data without scaling years
- updating auto_knot/manual_knot
- prevent problem of core program if version 0.2.4 with exeption and warning


### Problem of core program version 0.2.4:
- for degree=1: monotone regression with knot multiplicities cuase the solvers to hang
(fixed in version 0.2.5).


# BsplineQuantRegGui 0.2.1
### Changes
- add view human readable coefficents for the fitted spline
- add view derivatives (plots and coefficents)
- enhance R code output with additional information
- move demo in a demo tab
- enhance test with complete helper that copies the "FUNCTION SECTION" of the App.R


# BsplineQuantRegGui 0.2.0
###Changes
- add specific tests for the version
- add basis view tab
- add knot multiplicity management compatible with global
constraints and basis view
- improve  knots managenemt (removing, adding)
- secure end knots management, with multiplicity
