NEW: Create helper to assist with checking accepted/reject parameter types

[notmessenger]

Instead of having to copy/paste over and over things such as

// Function
assertionThrown = false;

try {
    something( function(){} );
} catch( error ) {
    assertionThrown = true;
}

ok( assertionThrown, 'Parameter was a Function' );

for each type wanting to check

sometimes specific values need to be set or a property on an object to get past some other assertion logic later in the code under test so needs to be definable beyond just a type.

Only implementing support for single-argument checking. #58 has been created to track development of support for multiple arguments.
