[BioC] make CDF env (fwd)

[w.huber at dkfz-heidelberg.de]

Hi Wenqiong,

since you seem to use the package "makecdfenv" from the "Developmental
Packages" section, please also use a recent version of "Biobase" from
there. The function "createPackage" is in there.

For the use of the make.cdf.env function, please see the vignette. You
need to make sure that the returned data from this function is stored by R
in a place where the affy library can find it (namely, in an "environment"
of the name XXXXXcdf.

Best regards
