## Description: ##

Similar to the db.myCollection.distinct() function, distinctTypes() will return

"types" rather than "values".  To accomplish this, it adds the following

function to the DBCollection prototype:  

```javascript

DBCollection.prototype.distinctTypes = function (keyString, query, limit, skip) {};

```

## Usage: ##

```javascript

// we hope this would return ['bson'] not ['bson','string']

db.users.distinctTypes('name');

// should return ['string']

db.users.distinctTypes('name.first');

// should return ['string']

db.users.distinctTypes('address.phone');

// only search documents that have { 'name.first' : 'Bob' }

db.users.distinctTypes('address.phone', {'name.first':'Bob'});

// only search the first 10 documents

db.users.distinctTypes('address.phone', {}, 10);

// only search documents 10-15

db.users.distinctTypes('address.phone', {}, 10, 5);

```

## Caveats: ##

By design, distinctTypes() returns 'bson' rather than 'object'.

It will return 'numberlong' rather than 'number', etc.
