New option in importGTF()

The importGTF() function has now an option to define numeric values during the import. This makes it easier to import expression data in gtf format. By default FPKM and TPM are imported as numeric values, but also other feature names can be given to the new option num.features

Update in importGTF()

The importGTF() function can now also import several gtf and merge them into one
output file. Further, the function offers now verbose feedback (if requested
with the verbose=TRUE option).

Another change is the skip option, previously the default was to skip the first 5
rows, now the default is ‘auto’. In auto mode all rows that start with ‘#’ are
skipped automatically.
