implements three commands:
type summary add <format> <typename1> [<typename2> ...]
type summary delete <typename1> [<typename2> ...]
type summary list [<typename1> [<typename2>] ...]
type summary clear
This allows you to specify the default format that will be used to display
summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes.
Examples:
type summary add "x = ${var.x}" Point
type summary list
type summary add --one-liner SimpleType
