add comment to explain code
add offset overlap when getting conditional U and B oligo target regions from U and D blocks
change attribute name from offset to overlap to avoid confusion
specify a u and d block overlap to enable design run to finish
ignore block oligo pairs that overlap, do not throw exception anymore as oligo regions can overlap
add design notes file
Merge branch 'devel' into oligo-block-overlap
make block overlap a option, defaults to 0, same as previous behaviour
