script/stdlib: add timing functions
speedup kernel calc using Y symmetry
demagkernel: also use X symmetry
demagkernel: also use Z symmetry
demag kernel symmetry: minor cleanup
add demagcube test
precise run time
temporarily disable kernel symmetry for test maintenance
fix gammaLL for precise timing
rm test/rk23, duplicate of stdproblem4 since rk23 became default
fix standardproblem4 for precise timing
fix standardproblem5a for precise timing
fix standardproblem4.go for precise timing
fix temperature test for precise timing
fix timedep tests for precise timing
re-enable kernel init symmetry, huge init speed-up
