Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide

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

This release introduces several improvements to fundamental geometric objects,
expands the numerical utilities in the tkz module, adds new capabilities for
conics, and clarifies portions of the documentation.

It continues the consolidation of existing methods while providing new tools for advanced geometric work.
Added
Points: New method length(p)
            Allows distance evaluation using z.A:length(z.B), equivalent to tkz.length(z.A, z.B).
Line:    Improved methods: orthogonal_at, collinear_at
            Both now behave more consistently in proportional constructions.
Circle: 
   New intuitive alias methods:
     from_radius ≡ through
     from_diameter ≡ diameter
     Updated common_tangent with more coherent handling of special cases.
Triangle:
   New method:
     trilinear_to_d — converts trilinear coordinates into distances to the sides (internally uses Heron’s formula).
tkz:    A set of highly useful numerical tools has been added:
   Generators and unit converters:
   tkz.range, tkz.deg, tkz.rad, tkz.pt
   Value checking: tkz.is_NaN, tkz.is_Inf, tkz.notDef
   Numerical analysis:
         tkz.fsolve(f, a, b, n [, opts]) — simple root finder
         tkz.derivative(f, x0 [, accuracy]) — numerical derivative at a point
Conic
   Added common_tangent for conics (currently implemented for ellipses).

Changed
Conic:
   The path method for ellipses has been redesigned:
   new modes: "swap", "ccw", "cw"
   proper handling of cases where the endpoints are opposite.

Documentation:
Corrected usage of
   \tkzDrawCoordinates[smooth]  (instead of \tkzDrawCoordinatessmooth) in the conic class.
   Added several new examples for CCL.
