Store asset information in JSON and load it using key value pair

GetAssetInfoEJ.md

What does this code do?

1. Fetch all the details of asset using Asset API's read() method.
2. Create JSON tree using JSON simple library and populate it with asset details from #1
3. Print an JSON tree having all the asset details
