reason: pointer abuse.
other than suspected, not correlated to changed j guessing in expr.cpp

BUT: TODO: crashed fitting leaves external processes as zombies

also still big problem with oy c();
also: plotting far to slow (using scalar)

strange inconsistency in expr.cpp hopefully fixed

cleanup: rm cv_intmode

several corrections to last functionality additions
sorted TODO

new commands 'mpaea', 'mpaer'
