An easy-to-use random number generator.

Randomizer(): Initializes the generator using a seed based on the current time.
Randomizer(long): Initializes the generator using a specific seed; useful for generating a repeatable stream of random numbers.

getDouble(double): Generate a random number using the default generator.
getDouble(double, double): Generate a random number using the default generator.
getFloat(float): Generate a random number using the default generator.
getFloat(float, float): Generate a random number using the default generator.
getInt(int): Generate a random number using the default generator.
getInt(int, int): Generate a random number using the default generator.
getLong(long): Generate a random number using the default generator.
getLong(long, long): Generate a random number using the default generator.
nextDouble(double): Generates a double value between 1.0 and the given limit.
nextDouble(double, double): Generates a double value between the given limits.
nextFloat(float): Generates a float value between 1.0 and the given limit.
nextFloat(float, float): Generates a float value between the given limits.
nextInt(int): Generates an int value between 1 and the given limit.
nextInt(int, int): Generates an int value between the given limits.
nextLong(long): Generates a long value between 1 and the given limit.
nextLong(long, long): Generates a long value between the given limits.
