New in Version 4.2.1

The major changes for this point release were to fix several problems with using
the built in editor to create new models and to bring the NXcanSAS reader into
compliance with the final published specification. The orignal reader was
based on a draft version of the specification. As an early adopter,
interpretation and implementation of the spec was iterated with all producers
of NXcanSAS reduced data known to the SasView team in order to ensure
compatibility and verify the implementation. A few other enhancements and bug
fixed were also introduced such as cleaning up the resolution section of the
fitting page GUI, increasing the max size range allowed in the corfunc
analysis, and adding the incomplete gamma function to the C library.
