test of normal distribution functions

[Prof J C Nash <nashjc uottawa ca>]

Morten is right that some values input for inverses tests are not fair 
to any spreadsheet processor. I hope to find ways to provide more 
informative output, that is, how the calculation fares in relation to 
what is reasonable at the default precision. The current example is VERY 
preliminary, and I simply copied values from one test to another.

Some of the more interesting tests are the bounds ones. These allow 
comparison with simple functions that can be locally computed. There are 
other examples of such functions, and a compromise is needed between 
different objectives to get a "nice" test.

For the moment I am avoiding the r.foo functions. Later on I hope to add 
to the Gnumeric-specific test files. For the moment I'm concentrating on 
ones that can be saved as .xls. I find these useful to send to Excel 
addicts.
