  Establishes a connection with a Snowflake database and provides methods for creating DataFrames and accessing objects for working with files in stages.

  Establishes a connection with a Snowflake database and provides methods for creating DataFrames and accessing objects for working with files in stages.

  When you create a `Session` object, you provide configuration settings to establish a connection with a Snowflake database (e.g. the URL for the account, a user name, etc.). You can specify these settings in a configuration file or in a Map that associates configuration setting names with values.

  To create a Session from a file:

      val session = Session.builder.configFile("/path/to/file.properties").create

  To create a Session from a map of configuration properties:

      val configMap = Map(
      "URL" -> "demo.snowflakecomputing.com",
      "USER" -> "testUser",
      "PASSWORD" -> "******",
      "ROLE" -> "myrole",
      "WAREHOUSE" -> "warehouse1",
      "DB" -> "db1",
      "SCHEMA" -> "schema1"
      )
      Session.builder.configs(configMap).create

  Session contains functions to construct DataFrames like Session.table, Session.sql, and Session.read

###

#### object implicits extends Implicits with Serializable

Provides implicit methods for convert Scala objects to Snowpark DataFrame and Column objects.

To use this, import `session.implicits._` :

    val session = Session.builder.configFile(..).create
    import session.implicits._

After you import this, you can call the `toDF` method of a `Seq` to convert a sequence to a DataFrame:

    // Create a DataFrame from a local sequence of integers.
    val df = (1 to 10).toDF("a")
    val df = Seq((1, "one"), (2, "two")).toDF("a", "b")

You can also refer to columns in DataFrames by using `$"colName"` and `'colName`:

    // Refer to a column in a DataFrame by using $"colName".
    val df = session.table("T").filter($"a" > 1)
    // Refer to columns by using 'colName.
    val df = session.table("T").filter('a > 1)
