Build fix.

setAll for iterable bool maps

Added the function isFinite(), and replaced the calls to finite() with it.
This was necessary because finite() is not a standard function. Neither can
we use its standard counterpart isfinite(), because it was introduced only
in C99, and therefore it is not supplied by all C++ implementations.

We do not use tolerance for excess, just for edges

clone => build renaming

Query functions have been implemented for GLPK (CPLEX breaks at the moment, I guess): These functions include:
retrieving one element of the coeff. matrix
retrieving one element of the obj function
lower bd for a variable
upper bound for a variable
lower and upper bounds for a row (these can not be handled separately at the moment)
direction of the optimization (is_max() function)

More sophisticated warning messages.

Fix 'unused variable' warnings

Oops. I did not mean to break the repository.

Some query functions got implemented, but only for GLPK.

Check for gcc version 3.3, 3.4 and 4.0 as well
