Several modules affected. Patch release: 1.2.1
writedat and tools were not loading
the pyclimateexcpt module and, thus, PyClimate exceptions
were not being catched by those modules.
The function detrend in mvarstatools module was
not working due to missing parent module names for some of the
Numeric and LinearAlgebra functions.

LanczosFilter.py
There's a problem with the normalization of the coefficients in
the Lanczos filter. For example, using LanczosFilter("lp",0.1,0.1,10),
the coefficients sum to 1.01.
Similarly the coefficients of a high pass filter should sum to 0. At the
moment one gets a non-zero high pass result even with a constant input.
This is true for low values of the number of coefficients of the filter.
But, in this case a more serious problem arise: the filter doesn't filter
correctly due to an enhanced Gibbs effect because of the
mathematics of the problem (see Duchon, 1979). This bug has NOT yet been
corrected. Therefore, the user is encouraged to use an adecuate number
of coefficients in the filter.

fix and test script: lftest.py)

atmosphericmoisture.py
The module atmosphericmoisture.py announced in version 1.2 was
not present in that distribution. The test crashes because of a
missing file testDO.nc.
