WIP lyx

[Danny Milosavljevic]

I have some work-in-progress lyx.  There is only ONE test failure left.  Any 
LATEX experts know what to make of it?

    (description "LyX is a document preparation system.  It excels at letting 
you create complex technical and scientific articles with mathematics, 
cross-references, bibliographies, indexes, etc.  It is very good for working 
with documents of any length in which the usual processing abilities are 
required: automatic sectioning and pagination, spell checking and so forth. ")
