Make some more things configurable:

*   Stroke color in area renderer can be a function that takes the graph color
    as a d3.rgb color and returns the color of the stroke
*   Format y axis ticks and totals values with a formatting function,
    `ticks_formatter` and `totals_formatter` respectively,
    just like `summary_formatter`.
*   Totals fields can be selected by passing an array of strings, e.g.
    `["max", "min"]`.
Add examples of `totals_fields`, `totals_formatter` and `tick_formatter`.
bumped to version 1.0.2
fixes #55

* adding explicit check for when min is undefined
FEATURE: upport for renderer: 'multi' in graphs and targets

- must use renderer: multi in graph
- must define particular renderer: within a target
- target's alias must match similarly as for color:

- giraffe.coffee to reflect JS code changes and re-generate the giraffe.js
- newest Rickshaw and d3 is used
updates to #58

* updated dashboards.js documentation
* updated coffee file to make sure the demo can display the multi render graph
* compiled coffeescript with latest version
updated to v1.1.0
fix typo in README.md
Moving the X axis down from graph and moving legend down if not the
legend will conflict with graph when the description is not there.
bump to v1.1.1
