I dig more into the two actors and found more differences:

1) sdf/lib/Repeat works with SDF, not PN (no output with PN director);
org/sdm/spa/Repeat works with PN, not SDF (only 1 can be set for SDF iterations
parameter)

2) sdf/lib/Repeat has a parameter called 'blockSize' and can accept a serial of
input tokens (e.g. from Ramp actor); org/sdm/spa/Repeat doesn't has such as
parameter, and only the first token is processed if a serial of input tokens
are sent to portInput port.

I don't know why org/sdm/spa/Repeat is built. My guess is that it tries to have
repeat behavior with PN.

With such big differences, it might not be a good choice to merge them. Maybe
we should updates their documents, having a 'see also' link to the other repeat
actor?
