Relocated the main tracker display files into rails app. Details on wiki.
ol3 files moved to the right place, new index.html.erb made for the ol3 map.
jQuery already available with jquery-rails gem, required in application.js
js require directives moved to application.js; directive syntax fixes; non-vendor testChart.js moved to app; dedicated ol3 folders
Images in rails located at app/assets/images/..., addressed as assets/...
app/assets/javascripts can be organized in any way, so put tracking_home js in their own dir.
Fixed another missing image file.
console output unnecessary.
More re-org, moved track_example js to own dir; Forgot to move testChart.js to tracking_home dir.
Clarifying comments on application.js directives.
More "Rails way" tracking_home integration: not a resource - don't need all those routes it makes, just one to index; js in .html.erb moved to .js.coffee as coffeescript; head removed - default provided by app/views/layouts/application.html.erb, customize with tracking_home.html.erb in layouts dir.
Easy startup to command line debugger with --debug option
Include pseudo-associations (model keys with _id) in expansion.
Temp file, shouldn't have been committed.
Minor logging error fixed.
