abstract: A user-friendly interactive Shiny interface for the 'BsplineQuantReg' package,
  enabling quantile regression using B-splines with shape constraints, based on the
  method described in Abbes (2025). Almost all parameters of the main function 'quantile_spline()'
  can be tuned. Features include interactive knot placement, per-region constraint
  specification, 'CSV' data import, direct demo access, reproducible R code generation,
  and solver selection. The version 0.2.2 handles knots multiplicity, Bspline basis
  visualisation, mean-square regression, pp form visualisation under human readable
  form, in local or canonical bases, The GUI provides two modes, basic (compatible
  with 'BsplineQuantReg' >= 0.2.2) and advanced (requires 'BsplineQuantReg' >= 0.2.5
  for stable multiplicity features). This GUI an improved version of the 'Python Tk'
  version of 'BsplineQuantRegPy'.
