Merge pull request #782 from RosettaCommons/dimaio/denovo_density_fixes
This pull requests add the de novo cryoEM model-building tools described from Wang et al. 2015 to public apps.
It introduces the new public app, 'denovo_density'. Additionally, it makes a few bugfixes to the spherical harmonic code, and introduces a new mover, electron_density/DockIntoDensity, a general mover for matching proteins structures to density maps through fast 6D search.
Additionally, several other miscellaneous fixes for modelling into cryoEM density are added in this checkin. This includes a number of accumulated bugfixes and new features to RosettaCM.
