ENDFtk v1.1.0

[whaeck]

This update adds additional interface functions to complete the human readable and ENDF speak interface for many objects:

• the NBT() and INT() interface functions to complement the boundaries() and interpolants() functions already present in TAB1 and TAB2 style components
• the numberInterpolationRegions() functions to complement the NR() function already present in TAB1 and TAB2 style components.

This update fixes the following issues:

• Older versions of ENDFtk sometimes read numbers like '2.0000000+0' as 1.999999999 instead of 2. The disco library was replaced with a new version included in the tools library that fixes this issue. In addition to fixing this issue, parsing ENDF files is now 10-20% faster.
