updated tooltip code
fixed bug with ordered multidimensions not filtering correctly
moved chart click to series; series now ignorant of dimensions; grouping wires up events between series clicks and chart groups (soon to be known as dashboards)
selected and nonselected items now being correctly highlighted on filtering
dashboard class added. fading of non-selected items now working, persisting between filters. Examples moved across to new DAshboard style
merged dashboard branch
fixed a bug with non string key values not filtering correctly
fixed bug with highlight function when multiple series are on same chart
update
Merge branch 'master' of github.com:scottlogic/insight
commit prior to modularization
moved all code inside the insight namespace
groupings are now created from a basic dataset, which feels much nicer.  Dashboard class probably not needed, moving globally needed functions into the singleton 'insight' namespace
added marker series, starting larger refactor back to valueFUnction() and keyFunction() instead of defining x and y, as they change depending on the chart/series orientation (vertical/horizontal)
marker targets work horizontally, refactored Scales to use a module defining the different types
fixed bug with horizontal marker series
