Implemented full treatment of xtal info and experimental technique
- some reshuffling of fields in PDBHeader and PDBCrystallographicInfo
- now xtal info is parsed from both PDB and mmCIF (before only from PDB)
- remove deprecated method getHeader/setHeader in Structure
- some additions to the Structure interface e.g. isCrystallographic
- StructureImpl.isNmr() is reimplemented to strictly signal NMR
structures (as the docs say), use nrModels() for multimodels
- a few deprecations
Missing class in last commit
Using reflection for all class names in mmcif parser
Added test for crystal info and some small fixes
Reducing verbosity of test, switch to full output setting VERBOSE=true
Updating integration tests to latest structure commits
