finally fix learning rate scheduling for real
...
okay, this is a disaster, but i think i've got it under control now.
the way batch-based learners now work is:
the epoch we're working towards is the truncated part of the epoch variable,
and how far we are into the epoch is the fractional part.
epoch starts at 1, so subtract by 1 when doing periodic operations.
