73a24ca0a9 remove '#include <iostream>' from headers and from unneeded places 
It's harmful to have iostream everywhere as it injects functions in the compiled files

Sparse matrix kernel (#6035) 
* Subtle bug in kernel computation

Coefficient was being passed by reference and, therefore, was
being changed indirectly.

In the process, updated the code to be more generic to avoid rational
computation in the middle of matrix manipulation.

* sparse_matrix: fixed handling of 0 in add_var() and add()

particularly in add_var(), without the fix the user is responsible for checking
coefficients for 0.

strict inequality (over reals) require solving for least-upper/greatest-lower bounds that may coincide with non-strict inequalities (be epsilon stronger). Instead of using the coefficient 'a' to turn the inequality into an equality, add the slack value as a constant.

e844aef896 remove a few more copy constructors, though still not enough to enable the assertion in vector 
I give up for now; there are too many copies left for little return..
