polelim example results in GSL ERROR

[GoogleCodeExporter]

I tried running the polelim example in the README file, which resulted in the 
following error:

$ ./polelim --effdist 0 --bkgdist 2 --bkgmeas 2 --bkgsigma 0.5 --nobs 4
Tools::calcIntRange() -> Unknown pdf type = 999

For some of the other examples I get slightly different output, in some cases 
because default values have changed, 

For one example I get a slightly different upper limit:
./polelim --nobs 30
result in  [ 17.812500, 47.708691 ]
whereas the README file states [ 17.81, 47.66 ]

Hello,
1. could you provide me with the exact output from ./polelim --nobs 30?

2. the first call fails since you have effdist 0 which is 'NONE'. As far as I 
remember this should be equivalent to the case when the efficiency is exactly 
known quantity.
It seems however that this functionality is broken. Need to look into that.

3. do you have details on system/compiler etc?

Thanks for your comments!

Fixed the issue with crashing code when the efficiency is set to be constant 
(--effdist 0).
Still need to trace down the cause for the difference in limits as observed.
