Printing Bit Vectors

A bit vector is printed as #* followed by the bits of the bit vector in order. If *print-array* is false, then the bit vector is printed in a format (using #<) that is concise but not readable. Only the active elements of the bit vector are printed.

[Reviewer Note by Barrett: Need to provide for #5*0 as an alternate notation for #*00000.]
