#group_by(input, property) ⇒ Object
Group an array of items by a property
input - the inputted Enumerable property - the property
Returns an array of Hashes, each looking something like this:
{"name" => "larry"
"items" => [...] } # all the items where `property` == "larry"

#sort(input, property = nil, nils = "first") ⇒ Object
Sort an array of objects
input - the object array property - property within each object to filter by nils (‘first’ | ‘last’) - nils appear before or after non-nil values
Returns the filtered array of objects

#tagged_with(input, tags, match = 'all') ⇒ Object
Filter an array of objects by tags
input - the object array tags - quoted tags list divided by comma match - (all- defaut, any, exclude)
Returns the filtered array of objects
