Adding API endpoint for endTickHeight in baseAxis

Close #612.
Height recomputed to max(tickLength,endTickLength)
Projectors w/data arg takes 1st datum - area/line

Wrapping projector in a function that will only take the first item in the dataset
Only if the projector looks for an attribute in the data

Close #744.
Removing function check
Add built files, update test and add linePlotTests
Merge branch 'master' of github.com:palantir/plottable into 612-end-tick-length
domainer accounts for scale.domain() === [x, x]
add scale.domain() == [x, x] test
Subclasses of baseAxis use maxLabelTickLength

maxLabelTickLength as so: if endTickLabels exist, use maximum of endTickLength, tickLength
If they don't exist, use tickLength
_projectToFirstDatum method

method specifically for area/line plots to apply projectors only on first datum
Bring axis stylings more in-line with Design's stylings.
