Determine if the given `err` satisfies the criteria defined by `matcher`:
- if `matcher` is a String, expect the error message to contain `matcher`
- if `matcher` is a RegExp, match the error message against it
- if `matcher` is a Function, call the function with `err` and return the result
- if `matcher` is an Error, expect their constructors to be the same
@param {Object} matcher error matcher
@param {Error} err error to match against
@returns {Boolean}
Determine if the given err satisfies the criteria defined by matcher : - if matcher is a String expect the error message to contain matcher - if matcher is a RegExp match the error message against it - if matcher is a Function call the function with err and return the result - if matcher is an Error expect their constructors to be the same
