Generic changes: - Genuinely unused variables (-Wunused-variable): delete them. Sometimes add a comment if the variable is for an extension of the code that isn't done yet. - Variables that became unused due to commented-out code (-Wunused-variable): comment out their definitions. Dirty, but that's because commenting out code instead of deleting it is dirty. Many of these are due to commented-out printlines that should have been log messages that only get emitted at high verbosity level. Specific changes: - SpikeObject.cpp (-Wunused-value): move initialization of loop variable into first for loop clause to silence the warning. Signed-off-by:Marti Bolivar <mbolivar@leaflabs.com>
