see mismatch with zone lookup and zone->inside check for muons. Try only for solenoid for the moment, until mismatch is understood.

added logic to look into the current zone which has been used by the AtlasFieldCache to cache the field description for one cell. The current zone has multiple cells, e.g. for all of the solenoid. This avoids re-looking up the same zone as one navigates out of a cell

ATLASRECTS-6655 : Returning a huge value (1.997kT) for the mag field , when none is present , from the getFieldZR creates issues. Return 0.1 Gauss in these cases

The function AtlasFieldCache::getField makes heavy use of Eigen and
runs extremely slowly in dbg builds.  Adjust to compile this function with
optimization, even in dbg builds.  For the MuonCombinedConfig unit test,
this results in a 20% speedup in the dbg build.

Add ATH_RESTRICT to addBiotSavart inputs, as they are tagged with it from the function calling it. Also check first if we are inside the r span of a cell BFieldCache::inside

Need to include <cstdlib> for size_t.

Magnetic Field Elements, small test fixes, add reference for the test, move more methods to .icc or .cxx

adding in unit test for field optimizations. This version is a detailed framework for testing, which will be simplified in further commits.

added LoadMapOnStart for AtlasFieldMapCondAlg for online running, and fixed the setting of UseSoleCurrent, UseToroCurrent for AtlasFieldCacheCondAlg so that they effectively turn off the field if set to 0

Use `Gaudi::Units` instead of CLHEP. Cleanup cmake configuration.

There is already a library that provides the public headers and hence
the `atlas_install_headers` is redundant.

Need <cstdlib> for size_t.
