slightly restructuring the project
added horizontal and vertical renderfunction combinators, and did some basic tests
cleaning up the code
The Matrix modulenow uses tuple indexed arrays instead of arrays of arrays. Also added a function to retrieve a sub matrix
a few little changes in the Matrix module
slightly generalized the interface of the Text module
Matrix uses the new text module to show a matrix now
MatrixTS compiling. Did basic testing as well
Math.Tree compiling. Although the pShow function can still be improved
improved Text module and fixed some bugs. Also added some little comments, and renamed some things
improved Math.Tree.pShow, it uses Text.TextBlock.divToLinesWE as a renderfunction now, which prints nice ellipsis if not enough space for a tree element
module Text.PrettyShow: added some space division functions, started to define quickcheck tests
went on defining test properties for quickcheck to test the Text module. Added a renderMatr function to Math.Matrix and Math.MatrixTS, which can render a matrix nicely (still experimental).
changes in the api of the Text module

it is now possible to call horizontal and vertical on empty lists. In that case the block will be filled to fill the given size. (an exception was called when rendering empty lists in former versions)
found the 'cabal haddock' command, and decided to delete the documentation fromthe repo.

the documentation can be created invoking 'cabal haddock' from the commandline from now on
slightly restructured the module Text. Added some documentation as well.
updated cabal file
divToLinesWE into autoNewLineWE
added some tests, also integrated them into the .cabal file. added some comments and documentation too.
added some doc
