Small test to see if using a literal buffer for keys in JSON decoder

improves memory usage. It does.

This test builds a large JSON string, decodes it into an interface{},

runs GC and prints memory stats.

To use standard decoder:

``` go

import (

	//"github.com/bserdar/jsdecodertest/json"

	"encoding/json"

)

```

To use the modified decoder:

``` go

import (

	"github.com/bserdar/jsdecodertest/json"

	//"encoding/json"

)

```

The jsdecodertest/json package is a copy of the standard library

encoding/json, with a literal map in the decoder

state. decoderState.objectInterface uses the literal map to store

field keys in a map.

Using standard library:

Alloc:401839488 

Use modified decoder:

Alloc:353839856 

This simple test only works when decoding into an interface{}.
