#initialize(*procs, template: nil, fields: nil, seperator: "\n", yes: 'true', no: 'false', **config) ⇒ Templated

Create a new output which will render using ERB. The provided template should only render the output for a single entry (aka model, record, data object, etc).

The template maybe either a String or a ERB object. Strings will automatically be converted to ERB with the trim_mode set to -.

A default template will be used if one has not be provided.
