Stack 1-D arrays as columns into a 2-D array.

Take a sequence of 1-D arrays and stack them as columnsto make a single 2-D array. 2-D arrays are stacked as-is,just like withhstack. 1-D arrays are turned into 2-D columnsfirst.

Parameters:	tup:sequence of 1-D or 2-D arrays. Arrays to stack. All of them must have the same first dimension.
