// # Author Helper
// Usage: `{{author}}` OR `{{#author}}{{/author}}`
//
// Can be used as either an output or a block helper
//
// Output helper: `{{author}}`
// Returns the full name of the author of a given post, or a blank string
// if the author could not be determined.
//
// Block helper: `{{#author}}{{/author}}`
// This is the default handlebars behaviour of dropping into the author object scope
