deprecated methods/properties/classes are being used within the code.

@function deprecation
@param {string} version - The version where the feature became deprecated
@param {string} message - Message should include what is deprecated, where, and the new solution
@param {number} [ignoreDepth=3] - The number of steps to ignore at the top of the error stack
       this is mostly to ignore internal deprecation calls.
