make sure it is actually easy to switch atom definitions during one work session

check why on certain machines the masses window gets displayed at
startup (Thanks Lionel Mamane)


implement support for the mzXML format

work on the calculation of isotopic ratios starting from formulas

write code to simulate graphically a mass spectrum with random noise
and monoisotopic peaks


As of the 18th september 2002 all is to be done, as this project
is born some minutes ago...

Check if g_strdup aborts the app if allocation failed
when  validating a polymer definition, it might be required that atoms be validated also
if (0 == strcmp ("\x0", code))
