Outline for new resource/material interfaces and notes.
first blush at sketching out new resource stack
cleaned up and simplified recipe library. tweaked/simplified public interfaces for Resource classes
made composition constructor private and added atom/mass basis factor funcs
removed unused scratch folder
renamed mat and res files to full length
updated all core code to use new resource classes.  Added extractRes method to resource interface to facilitate resourceBuff and market order splitting
Updated material tests. Added unit consts to Material.h. Made material constructor protected to facilitate testing via subclassing
fixed most of the tests. Fixed a bug in Material::extractComp. Created MatQuery class and used it to fix bug in Enrichment class
fixed units bug. Fixed material extract bug. Compositions must be in mass basis for mixing ratios to be meaningful - this will require a conversion before passing to the decay handler.
removed mix from composition class. made composition track atom and mass internally
fixed Material extract/absorb tests
material constructor records state in output db.
made resource subclasses friends of resource to facilitate modification of protected/private members outside of 'this' context in factory creation and cloning methods. Re-ordered implementation and header methods to be consistent.
added default arg for resource in transaction constructor
fixed enrichment bug. extended matquery to support fractions. Fixed self-parent-id bug for initially created resources
added ability to set resources as untracked in create factory funcs
Fixed bug in composition decay. Cleaned up resource heritage tracking - fixed it and added stateId to resource interface.
fixed bug from uninitialized class member POD var. Cleaned up decay handler a bit
fixed bug in prev_decay_time initialization in materials. Increased event manager buffering
