alln and anyn: N-D "all" and "any" function

Improved version of the built-in "all" and "any" fuction, designed for higher-dimension input

ALLN(A) is similar to all(A), but always returns a single value which determines if all matrix elements are nonzero. When A is a 2-D or higher-dimension matrix, it will return the same result as all(reshape(A, 1, [])).
ANYN(A) is similar to any(A), but always returns a single value which determines if any matrix elements are nonzero. When A is a 2-D or higher-dimension matrix, it will return the same result as any(reshape(A, 1, [])).
Both functions are useful when A can be either scalar, vector or matrix in your scripts.
