# Insert is a persistence command responsible for taking a document that
# has not been saved to the database and saving it. This specific class
# handles the case when the document is embedded in another.
#
# The underlying query resembles the following MongoDB query:
#
# collection.insert(
# { "_id" : 1, "field" : "value" },
# false
# );
class InsertEmbedded < Command
# Insert the new document in the database. If the document's parent is a
# new record, we will call save on the parent, otherwise we will $push
# the document onto the parent.
#
# Example:
#
# <tt>Insert.persist</tt>
#
# Returns:
#
# The +Document+, whether the insert succeeded or not.
