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

haehnel: spelling mistakes fixed

alvarado: Example for dynamic_cast fixed.

alvarado: C++ header files used instead of C header files

alvarado: Do not forget using parameters set by the user using the dialog.

sltilib: include only ltiMath.h instead of standard cmath header to cope
just in one place with different compiler/libraries inconsistencies.

alvarado: implementation of the protected inline function enterPX now in header.
It is used by some child classes.

sltilib: MS Visual C++ does not support the standard C++ headers as it should.
Functions defined therein are not in namespace std.
Many changes towards a standard use of the headers need to be rolled back.
ARRGGHHH

sltilib: Problems with functions in C++ headers fixed. They are
not in the std namespace

alvarado: C++ header files used instead of C header files.
Bugs with statusString fixed (not initialized in copy constructor, not deleted in destructor)

alvarado: @ADD ioHandlers administrate now a status string, as functors and classifiers also do. This allows reporting of error when reading or writing data to (or from) a file.
