eq_iv - tests for content equality between vectors of integer
array array -> bool
Deep equality test since regular eq is an identity test for vectors
Intent is to be used in mathematica.sli to override eq for intvectortype.
Example:
<# 1 #> <# 1 #> eq_ --> false
<# 1 #> <# 1 #> eq_iv --> true
two arrays of integers
