Validation framework

This pattern grew out of existing Intent data extraction code.

Goals

* abstract away the details of processing
* provide informative errors and warnings
* self documenting usage
* able to report multiple findings (warnings)
* fail assertions in acontrolled manner, not by throwing

Sample usage:
```
    fun readArgs(
       val bundle: Bundle
    ) = validateFrom(bundle::get): ValidationResult<ExampleObject> {
        val intValue = required(value<Int>("KEY_1"))
        val stringValue = required(value<String>("KEY_2"))
        val arrayValue = optional(array<String>("KEY_3"))
        val doubleValue = optional(value<Double>("KEY_4"))

        ExampleObject(intValue, stringValue, arrayValue, doubleValue)
    }
```
