-------------------------------------------

Do you think you could add a Datasource-catalog to list all available datasources..?

> Add an interface to save and load table sources similar to Java's {{Serializable}} interface. 
> TableSources should implement the interface to become saveable and loadable.
> This could be used as follows:
> {code}
> val cts = new CsvTableSource(
>   "/path/to/csvfile",
>   Array("name", "age", "address"),
>   Array(BasicTypeInfo.STRING_TYPEINFO, ...),
>   ...
> )
> cts.saveToFile("/path/to/tablesource/file")
> // -----
> val tEnv: TableEnvironment = ???
> tEnv.loadTableSource("persons", "/path/to/tablesource/file")
> {code}
