ENH: Add geomspace function
Like logspace, but specifying start and stop directly, without having to
specify the base.
Purely imaginary or purely negative real sequences are converted to
positive real, computed, and converted back, so there are no negligible
real or imaginary parts. Instead of
array([ 6.12323400e-17 +1.00000000e+00j,
6.12323400e-16 +1.00000000e+01j,
6.12323400e-15 +1.00000000e+02j,
6.12323400e-14 +1.00000000e+03j])
it outputs array([ 0. +1.j, 0. +10.j, 0. +100.j, 0.+1000.j])
If dtype is complex it does the math in complex so it can leave
the real line and follow a spiral.
TST: Added tests for geomspace and more tests for logspace, making
PhysicalQuantities tests work for all types of functions
PEP8: __all__ after imports, line wrapping
