smearer does not handle negative q values (Trac #490)

[butlerpd]

the new module resolution.py assumes all q will be positive. This may not always be true (cuts of a 2D set for example or USANS rocking cure. Question is how to properly handle. Readers could be required to absolute the q values or discard them (what will a model do with negative q?) otherwise need to verify that all models are robust to fitting negative q.
