Helper functions for Handlebars
ifLastObj function: This is to resolve the issue where Handlebars will not provide a method to know when you've reached the last item in an object. They only do so for Array's with @last. Both Array and Objects can use @first though
Example:
{{#each arrayObj}}
{{#ifLastObj @index ../arrayObj}}
{{this}}
{{else}}
{{this}},
{{/ifLastObj}}
{{/each}}
