Compute breaks for continuous scale.

This function wraps up the components needed to go from a continuous range to a set of breaks and labels suitable for display on axes or legends.

cbreaks(range, breaks = extended_breaks(), labels = scientific_format())
numeric vector of length 2 giving the range of the underlying data
either a vector of break values, or a break function that will make a vector of breaks when given the range of the data
either a vector of labels (character vector or list of expression) or a format function that will make a vector of labels when called with a vector of breaks. Labels can only be specified manually if breaks are - it is extremely dangerous to supply labels if you don't know what the breaks will be.
