Methods
-----------
#### getFunctionName(function)
Attempts to safely determine name of a named function
returns string or null if undefined
example:
``
var f = function testing() {};
console.log( Fun.getFunctionName(f) );
#### getConstructorName(function)
Attempts to safely determine name of the Class Constructor
returns string or null if undefined
example:
`
var d = new Date('05/Nov/1605');
console.log( Fun.getConstructorName(d) );
#### construct(constructor, args)
Invokes a Constructor with optional arguments array
example:
`
console.log( Fun.construct( Date, '5/Nov/1605' ).toString() );
#### factory(args)
Returns an arbitrary Function from array
example:
`
console.log( Fun.factory( ['a,b', 'return a + b'] )(2,2) );
#### fromString(string)
Creates function from string (simple functions only -- does not support nesting)
example:
`
str = 'function (a, b) { return a+b; }';
console.log( Fun.fromString( str )(2,2) );
#### toString(function)
Converts function to string, using encoding to handle native objects (simple functions only -- does not support nesting)
example:
`
var f = function (a,b) { return a + b; };
console.log( Fun.toString( f ) );
