LiftUp format

liftUp needs a lift-file.

The format is:

offset oldName oldSize newName newSize

An example:

 0       frag1   1000    chr1    5000
 1001    frag2   1000    chr1    1000

Typing this command:

 liftUp stdout -type=.bed test.lft warn test.bed

will lift the following feature

 frag2   1100    1200    voila

to the following one:

 chr1    2101    2201    voila
