### Purpose
###  * Functions to save the output of time consuming functions to memory and
###    return results quickly if we already have the answers
### 
### Notes: Standard usage would go like this
### FunctionName <- function(){
###   args          <- c(as.list(environment()), list())

examp1 <- "When discussing performance with colleagues, teaching, sending a bug report or 
searching for guidance on mailing lists and here on SO, a reproducible example is often 
asked and always helpful. What are your tips for creating an excellent example? How do 
you paste data structures from r in a text format? What other information should you 
include? Are there other tricks in addition to using dput(), dump() or structure()?

/**
 * This is a very simple example of an ember component to integrate
 * nnick/chart.js in an ember.js application. Basically, it is simply
 * using the components hook to create a ChartJS canvas element.
 * Additionally, it supports an update property that allows you to
 * let the chart re-rendet if your data or options change. Chart.js
 * doesn't support updating its data so this will just create a new
 * chart on the given canvas.
 * 
 * Example usage in a handlebars template:
