/**
* Create a string corresponding to a valid declaration and initialization of an Objective-C object literal.

* @param nsClass Class of the litteral
* @param name Desired name of the instance
* @param parameters Key-value object of parameters to translate to an Objective-C object litearal
* @param indent If true, will declare the litteral by indenting each new key/value pair.
* @return A valid Objective-C declaration and initialization of an Objective-C object litteral.
