Table to errorbars

[vascotenner]

I like to create an errorbarplot from a table, this is closely related to #103 .

table.to.errobars(x,y,yerr)

This has now been added along with a spreadfn argument to reduce/collapse/aggregate methods. You can see an example of the usage here #103 (comment). If you have a Table containing an column corresponding to the error you can call table.to.errorbars(['x'], ['y', 'yerr']). I'll also be adding a new Tutorial with some examples of this.

Closing this issue now.
