Summary description:  Unicode algorithms for LuaTeX

Announcement text:
 Lua code working with Unicode data has to deal with quite
 some challenges.  For example there are many canonically
 equivalent sequences which should be treated in the same way,
 and even identifying a single character becomes quite different
 once you have to deal with all kinds of combining characters,
 emoji sequences and syllables in different scripts.
 Therefore lua-uni-algos wants to build a collection of small
 libraries implementing algorithms to deal with lots of the details
 in Unicode, such that authors of LuaTeX packages can focus on their
 actual functionality instead of having to fight against the
 peculiarities of Unicode.
