Requirement
Add 1D and 2D Array Extension and one-based array methods for populating an array with a constant. Note: we can always just do a map and pass in a lambda for setting the constant value, then copy all the values from the mapped array to the source one. Or we could use Linq. But the point here is efficiency - the update of a constant value doesn't pose the same threat of some exception being thrown mid-way through as population with a lambda, so we should in this case update in place.
Clearly document that the update will happen in-place, and if an exception does somehow happen e.g. due to some threading issue, then the array will end up in a partly populated state - although it's not clear how a unit test could even be written for that.
Value Proposition
A fast update for initialisation of a constant value will allow arrays of constants other than the default value to be efficiently initialised.
Design Ideas
Use a for-loop - just like is done here: https://stackoverflow.com/a/1014015/5134722.
