pick_events()

std::vector< Stock_event > pick_events	(	const std::vector< Stock_event > &	all_events,

Pick a random event from the list of events.

Parameters

all_events	The list of all events
num_events	The number of events to pick

Returns

A vector of Stock_event

Todo

Optimize this loop so that we don't have to calculate the total_permille every time we pick an event.

When picking the event, consider event.probability_permille. E.g. if there are 3 events with probability_permille 10, 20, 30. total_permille = 60; random_permille = 0 to 59; If random_permille is 0 to 9, pick the first event; If random_permille is 10 to 29, pick the second event; If random_permille is 30 to 59, pick the third event.
