prerelease checks

[Brian Gough]

Interesting. This is what I get,

 PASS: miser(f1), dim=7, err=0.0266 (0.963855 observed vs 1 expected)
 PASS: miser(f1), dim=9, err=0.0693 (0.9571 observed vs 1 expected)

The first case is pretty similar. The second case seems to be
significantly different.  I have no idea why it should be.

A long shot: if the environment variables GSL_RNG_TYPE or GSL_RNG_SEED
were set when you ran the tests then that would affect the
results. (We should definitely modify the monte functions not to
depend on the environment variables and to take a generator as an
extra argument).
