Optimize Graphing

[coatless]

To do list:

1. Begin process of abstracting parts of the imu graphing procedure to align with multivariate time series.
2. Move out parameter checks into their own callable function.
3. Switch to *apply's from for loops when possible.
4. Use roxygen2 templates
5. Rewrite the addSpaceIfDuplicate function to use duplicates() to remove a double for loop....
6. ...

Regarding 2., one can modify environments like so:

m = function(){
  g()
  wyang
}

g = function(o = parent.frame()){
  assign("wyang", "Wenchao", envir = o)
}
