 This package provides a common system for string templating across the Budibase Builder, client and server.
 The templating is provided through the use of [Handlebars](https://handlebarsjs.com/) an extension of Mustache

 We have not implemented all the helpers provided by the helpers package as some of them provide functionality
 we felt would not be beneficial. The following collections of helpers have been implemented:

 for use with arrays, useful for example in automations. Helpers like `first`, `last`, `after` and `join` 
 can be useful for getting particular portions of arrays or turning them into strings.

 for building up particular URLs to hit as say part of an automation.

 building strings when particular conditions are met, for example `and`, `or`, `gt`, `lt`, `not` and so on. This is a very
 extensive set of helpers but is mostly as would be expected from a set of logical operators.

+9. [Date](https://github.com/helpers/helper-date) - last but certainly not least is a moment based date helper, which can
 format ISO/timestamp based dates into something human-readable. An example of this would be `{{date dateProperty "DD-MM-YYYY"}}`.
