ui-obj
Easily create plain objects with computed keys as meteor ui helper.
Useful to set the context of the current scope e.g. for iron-router
paths.
{{#with $obj "one" 1 "two" 2}}
sets context to
{one: 1, two: 2}
Merge the context within a each
block with the outer context
{{#each items}} {{#with $obj .. .}}
