Package dealing with LImit ROots of COxeter groups (eternal Beta version)

This package deals with limits roots of infinite Coxeter groups and related structures. It allows to compute several related objects such as matrices representing the elements, roots, weights, and obtain properties of the representation. Further, it allows to visualize the isotropic cone, the roots, the weights, the limit roots, and the Tits cone in the affine space spanned by the simple roots.

The current version is 1.0.0.
