Quick Start with HestiaStore

Index should be created with builder, which make index instance. For example:

// Create an in-memory file system abstraction
Directory directory = new MemDirectory();

// Prepare index configuration
IndexConfiguration<String, String> conf = IndexConfiguration
        .<String, String>builder()//
        .withKeyClass(String.class)//
        .withValueClass(String.class)//
        .withName("test_index") //
        .build();

// create new index
Index<String, String> index = Index.<String, String>create(directory, conf);

// Do some work with the index
index.put("Hello", "World");

String value = index.get("Hello");
System.out.println("Value for 'Hello': " + value);
