Returns an accumulator function which incrementally computes a minimum absolute value.

@returns {Function} accumulator function

@example
var accumulator = incrminabs();

var min = accumulator();
// returns null

min = accumulator( 3.14 );
// returns 3.14

min = accumulator( -5.0 );
// returns 3.14

min = accumulator( 10.1 );
// returns 3.14

min = accumulator();
// returns 3.14
