/**
 * Gets the child nodes of a PHP double quoted string psiElement and maps them to a List of String values. Allows to
 * specify a callback function for processing string literal fragments, and other for embedded variables and
 * expressions. Delimiter double quotes are omitted since their presence is constant.
 *
 * @param psiElement               The PHP double quoted string literal whose nodes are wanted to map
 * @param stringFragmentMapper     A Function implementation which gets a String from the ASTNode of any string
 *                                 literal fragment on the PHP string. Any node which lead to a null return value
 *                                 will be omitted from the result.
 * @param embeddedExpressionMapper A Function implementation which gets a String from the ASTNode of any variable or
 *                                 expression embedded on the PHP string. Any node which lead to a null return value
 *                                 will be omitted from the result.
 * @return A List of String objects containing the results of sequentially applying the PHP string pieces to the
 * provided Function implementations as determined by the node type.
