LTI-Lib (C++ Computer Vision Library) Code

sltilib: Visual C++ couldn't cope with the "type& var(init);" syntax.
Workaround added type& var=init;

sltilib: Two errors fixed:
1. classes sqrType changed to struct, in order to make
the typedef public
2. Visual C++ STL could not insert list elements into a vector,
so that the node::add() method for lists needed to be
reimplemented.

sltilib: Explicit instantiation of abstract class produced a
warning. Warning disabled.

harte: Much more documentation added

weiler: verry little monday morning bug fix

alvarado: Clean targed added.

alvarado: Missing inconsistency check added, for detected blobs segments the are isolated pixels

alvarado: Link to SourceForge icon changed.
