Summary description: Draw highly accurate pH titration curves using TikZ and pgfplots

Announcement text: ------------------------------------------------------------------------

I am pleased to announce the initial release (v1.0.0) of
the phtitration package.

This package provides LaTeX macros to render highly accurate
pH-metric titration curves using TikZ and pgfplots.
By employing exact mass and charge balance parametric equations,
it ensures smooth, continuous curves without the visual breaks
typical of piecewise approximations.

Key features:
- Supports 8 standard acid-base titration types (including polyprotic).
- Automatically draws the tangent method (m|-thode des tangentes) at
equivalence points.
- Highly customizable styles, coordinate labels, and units.

Thank you!
