Get and Set using JavaScript notation

Before (yeah it scrolls):

// set the city
data.(map[string]interface{})["addresses"].([]interface{})[0].(map[string]interface{})["city"] = "London"
// get the city
city := data.(map[string]interface{})["addresses"].([]interface{})[0].(map[string]interface{})["city"]

• Panics if any piece is missing or wrong type

After:

m.Set(data, "addresses[0].city", "London")
city := m.Get(data, "addresses[0].city")

• Returns nil if any piece is missing or wrong type
• Use GetOK for a second argument bool

m's Issues

Can only access array data if it is nested

data := make([]map[string]interface{}, 1)
m.Set(data, "[0].address.city", "London")
// city should equal London
city := m.Get(data, "[0].address.city")

The above code won't work.

Set should create maps if they don't exist

@matryer can you clarify the license on this package? The godoc won't display due to the lack of license: http://godoc.org/github.com/matryer/m

Add Delete and DeleteOK

Deleting deep things would be helpful too.
