These allow for a given block to be wrapped in helper methods or metadata and allow for more control over the current container and method before the code is run.
Converts the tool chain to use babel, eslint, and webpack vs. the previous proprietary solutions.
Additionally begins enforcing additional linting concerns as well as updates the code to reflect these rules.
Fixes#855Fixes#993
Allows users to chain multiple helpers together using their inverse callbacks. I.e.
```
{{#if foo}}
{{else if bar}}
{{else}}
{{/if}}
```
The control flow here effectively causes the helpers to be nested. The above is actually syntactic sugar for this:
```
{{#if foo}}
{{else}}
{{#if bar}}
{{else}}
{{/if}}
{{/if}}
```
Any helper may be used in this manner, the only requirement is they support normal calls and inverse calls.
Introduces a breaking change in that `{{else foo}}` may no longer be used as a root level operator. Instead `{{^foo}}` must be used.
Fixes#72.
Provides the mustache behavior of recursive lookup without the use of depthed paths.
Note that this does incur a fairly dramatic performance penalty for depthed queries.
