added lineScatter.yaml with universal plotting stuff

[wdwatkins]

Might want to change the name of this config?

Coverage remained the same at 76.755% when pulling 28e4d25 on wdwatkins:master into 4bfd0c4 on USGS-R:master.

To load the config file:

loadConfig('inst/extdata/lineScatter.yaml')
set.seed(2576)
X <- runif(33)
Y <- runif(33)

gs <- gsplot() %>% points(X,Y,xlab="X",ylab="Y") %>% axis(c(3,4),labels=FALSE)

@wdwatkins I think if you have the most recent (master on USGS-R/gsplot) you would see a box, right?

Also, for those loading the package (w/o the source in inst)

loadConfig(system.file('extdata', 'lineScatter.yaml', package = 'gsplot'))
set.seed(2576)
X <- runif(33)
Y <- runif(33)

gs <- gsplot() %>% points(X,Y,xlab="X",ylab="Y") %>% axis(c(3,4),labels=FALSE)

@jread-usgs Yes, I wasn't updated. Had some weird build problems.
