convenient spring jdbc methods

1a) Query for map - if your query/proc returns just a single row and you
don't want to create a new bean class.
* Column names had better be distinct, which is usually easy.
* Similar to boost tuple.
2) Query for object (of your custom class) - if your proc/query returns
a single row, and you already have a bean class to hold all attributes.
3) queryForObject (String sql, String.class) - if you are sure to get
only one row and combine all columns into a single string
4a) Query for int - if your query/proc returns nothing but an integer
4b) Query for object - if your proc/query returns a single Date
5) Row mapper - if your query/proc returns a result set
