./current
Lookup a value in only the current context.
    ./key
  
  Only looks up key in the current context.  Returns undefined if
not found.
{{#each(todo)}}
  <input {($checked)}="./complete"/> {{./name}}
{{/each}}
  
  
  
Use
Sometimes, especially with recursive templates, you want to control which
context is used to lookup.  Adding ./ before the key name will
only look up in the current context.
The following template:
{{first}} {{last}}
  {{#children}}
    {{first}} {{./last}}
  {{/children}}
Rendered with:
{
  first: "Barry", last: "Meyer",
  children: [
    {first: "Kim", last: "Sully"},
    {first: "Justin"},
  ]
}
Writes out:
Barry Meyer
    Kim Sully
    Justin
Notice that {{./last}} returns nothing because there's no last property
in the {first: "Justin"} object.
