Parse function(x) x+1

f=function(x) { x+1}; 7  vs  // define f as incr; return 7
f=function(x) {x+1; 7} vs  // define & return f as a fcn returning 7
f=function(x) x+1; 7 // define f as incr; return 7
Fix VEN-1
Beef testing to match new parser

Rotate apply(,2,) results 90 degrees

Had results sideways; now as.data.frame(apply(...)) always returns 1-col
x N-rows for apply(,1,) and apply(,2,).  Runit_v_3_apply.R now passes.
renamed since passing

force header=0 so the offending (dup col names) header row is NA'ed

apply(,1,) - was turned 90 sideways

Set the default final momentum for NN back to 0.99 (should be <1.0).  Note that
this is just a heuristic number and the previous default value.  For now, the
user is expected to find optimal parameters via a grid search.

Enable support for momentum in the NN reference implementation, using float for weights and double for biases, similar to H2O.
Demote "Start remote task#" and "Done  remote task#" from Info level to Debug level.
Reproduce NN reference results, and expose a ConfusionMatrix bug.
Fix typo.
Remove comments.
