Flatten PMMatrix

[SergeStinckwich]

Transform a 2D arrays (PMMatrix) as an 1D vector (PMVector).

a := PMMatrix rows:#((1 2) (3 4) (5 6)).
a flatten.

=> a PMVector (1 2 3 4 5 6)

testFlattenOnColumns
	| m |
	m := PMMatrix rows: #(#(1 2 3) #(4 5 6) #(7 8 9)).
	self assert: m flattenOnColumns equals: #(1 4 7 2 5 8 3 6 9) asPMVector

testFlattenOnRows
	| m |
	m := PMMatrix rows: #(#(1 2 3) #(4 5 6) #(7 8 9)).
	self assert: m flattenOnRows equals: #(1 2 3 4 5 6 7 8 9) asPMVector

Hi Serge, why not just flattenRows and flattenColumns?
