Started

`NEWS.md`

.Replaced some LaTeX symbols,

`\textrm`

->`\textnormal`

and`lVert`

->`||`

(same for`rVert`

), to fix LaTeX compilation issues in the`r-oldrel-macos-arm64`

when creating the PDF documentation file.Added

`#include<cmath>`

to`medianheuristic.cpp`

and switched from`std::abs`

to`std::fabs`

in that file; otherwise seemed to be ambiguous to compiler for`r-oldrel-macos-x86_64`

.Added energy distance method

`energydist`

, which is computed naively.
