- converted classes for stencils, tables and factories to templates
- added backward compatible class wrappers around new templates
- extended PatchTable to support variable precision stencil tables
- extended PatchTableBuilder to manage PatchTable's new stencil tables
- templated PatchTableBuilder conversion from SparseMatrix to stencils
- extended public PatchTableFactory interface to specify precision
- converted PrimvarRefiner class to template and added wrapper class
