Generate default message from provided name

[jtheriault]

As a convenience coerce should generate a default message based on a provided name for the value being coerced.

Example

${name} should be coerceable to ${type.name}. Provided value: ${JSON.stringify(value, null, 2)}

This may require a major version to continue allowing a complete message to be provided

After our discussion last week, I made an attempt at having an overloaded method that would accept and object as the first parameter. That was definitely a no go. We cannot be confident that the first parameter is not already an object causing the validation for this to be sketchy at best.

I'm going to make an attempt at the 3rd parameter being an options object, as that was the other alternative we had discussed.

PR amended with third parameter being allowed to be an optional object
