added the possibility to truncate A and P.
...
P can now be truncated by specifying a truncation factor through -Ptr <xxx>
and/or specifying the max. no. of elements per row desired through
-Pmx <nnn>
A can be truncated by specifying a truncation factor through -Atr <xxx>
Truncation for A is done by determining the max diagonal element , and
eliminating every off-diagonal ellement smaller than the max diag.elmt *trunc
factor and adding this element to the diagonal
Truncation for P is done by eliminating every element per row smaller than
the abs. max elmt of this row * trunc-factor, and renormalizing the row
after truncation (or determining the max. k elements per row , eliminating
the others and renormalizing)
