changed tabs to spaces in slider.
changed slider config.format property from function to format specifier string.

This is going to be needed when trying to put the config for a slider in the activity config instantiated by the BricLayer.

Slider changes to config
1st pass at creating config for NeffBarAnim.html, page is currently broken

Config has sections for all containers and brix on the page.
Need to add data to the config
Need to add configFixup to reference the data
Need to change some brix so their config contains a d3 format string not a d3 format function.
Add datasets to activity config in NeffBarAnim.html
Get the data section of the activity config working

Still needs unit tests. Also added a couple more types of dynamic values:
array
array-element
Unit tests for new functionality in BricLayer

tests were added for:
- new data section in config
- new _array_ dynamic value type
- new _array-element_ dynamic value type

also fixed wrong dynamic value type value in activity schema
