nonnegativity

-----------------------------+----------------------------------------------
the documentation on MixedIntegerLinearProgram().new_variable does not
mention that by default the corresponding variables are assumed to be
nonnegative.
The only place this is mentioned is
[http://www.sagemath.org/doc/thematic_tutorials/linear_programming.html LP
Thematic Tutorial]. It says:
"By default, all the LP variables are assumed to be non-negative reals.
They can be defined as binary through the parameter binary=True (or
integer with integer=True). Lower and upper bounds can be defined or re-
defined (for instance when you want some variables to be negative) using
the methods set_min and set_max."
This must appear in regular docs, too.
