Mapping modifiers

Mapping a function over an array means to call it on each element of that array, creating an array of results. It's also possible to map over two arrays, applying the function to various choices of one element from each, but there's no longer a single correct way to iterate over these elements.

BQN has two 1-modifiers to map over arrays: Each (¨) and Table (⌜). On two arguments, Table applies its operand to all combinations of elements while Each creates a one-to-one or one-to-many matching. Since they apply to elements, these modifiers are different from Cells (˘) or its generalization Rank (⎉), which apply the function to array cells. The modifier Depth (⚇) is a generalization of Each, so that ¨ is ⚇¯1; however, it can't be used to implement Table without some additional array operations.
