Returns target object's value pointed by pointer, returns undefined
if |pointer| points to non-existing value.
If pointer is not provided, validates first argument and returns
evaluator function that takes pointer as argument.

@param {Object} target
@param {string} [pointer]
@returns {*} pointer JSON Pointer string
Returns target object s value pointed by pointer returns undefined if |pointer| points to non - existing value . If pointer is not provided validates first argument and returns evaluator function that takes pointer as argument .
