Code Changes, Features

Title	Change	Impact on Requirements	Author	Reviewer(s)	PR
Providing better composite iteration methods	Provide ways for users and developers to traverse the composite tree without using lists.	This very slightly simplifies the implementation I_ARMI_FLUX_COUPLING_VALUE, and very slightly touches the test T_ARMI_FLUX_COUPLING_VALUE. This also, very slightly, simplifies the implementation I_ARMI_ASSEM_DIMS1 and I_ARMI_CMP1 with the new tools this PR provides.	Drew Johnson	John Stilley	2031
Adding a check on the grid/component consistency in the BPs	Adds a check on the grids associated with a block to ensure that the components that are supposed to be in the grid actually are, and in the correct number.	This change very slightly touches the unit test T_ARMI_BP_GRID0 for the requirement R_ARMI_BP_GRID.	Chris Keckler	John Stilley	2045
Allowing ARMI to use tmp dir on Mac/Linux	Moving from the home directory to the temp direction on Linux, for ARMI temp files.	NA	John Stilley	Arrielle Opotowsky	2092
Removing support for XML geom files	Removing support for archaic XML “geom files”, in favor of modern YAML blueprint files.	NA	John Stilley	Arrielle Opotowsky	2105
Add Core.iterBlocks and Assembly.iterBlocks	Adding Core.iterBlocks and Asssembly.iterBlocks for traversing grandchildren of a Core.	A trivial implementation change to switch from getBlocks to iterBlocks in the tests for T_ARMI_MACRO_XS, T_ARMI_UMC_PARAM_BACKWARD0, T_ARMI_UMC_PARAM_BACKWARD1, T_ARMI_ROTATE_HEX_ASSEM, T_ARMI_ASSEM_BLOCKS, T_ARMI_R_SYMM, and T_ARMI_ADD_EDGE_ASSEMS.	Drew Johnson	John Stilley	2106
Handing empty string defaults better in copyInterfaceInputs	Adding logic to copyInterfaceInputs to properly handle a file setting default that is an empty string.	NA	Arrielle Opotowsky	John Stilley	2107
Allowing component area to be queried at arbitrary temp	Allow calculation of component area at arbitrary temperature	NA	Alex James	John Stilley	2114
Adding a FilletedHexagon shape	Adding a FilletedHexagon shape, which is just a hexagon with rounded corners.	NA	John Stilley	dlangewisch, Chris Keckler, Alex James	2118
Supporting growing DBto full core on db load	The setting growToFullCoreAfterLoad is used to expand the reactor to full core when loading from a database.	Functionality added to I_ARMI_DB_TIME1 the implementation of R_ARMI_DB_TIME	Drew Johnson	John Stilley	2121

Code Changes, Bugs and Fixes
