Ensure that ingredient_amounts added have a valid unit type
Removed pluralize method, doesnt work that great
Added some extra conversions

However, there is an issue with alchemist with a bug for adding a new conversion
type (version 0.1.5).  Need to compile from source!
Updated alchemist to fix adding a new conversion type
Added better message for a valid unit type
Added another feature request
another feature requrest
Added another name for a deviation
Added more validations

Specifically, units will be converted to lower case to ensure unformity, there
must be a valid ingredient associated with the selection, and the amount must be
a number
Merge branch 'alchemist_addition' into development

There is now a unit library backend for validating and converting units
