iFit/isvector

PURPOSE

SYNOPSIS

DESCRIPTION

 b = isvector(s) : True for vector iData object

   @iData/isvector function to return true if data set is a vector
   i.e. that its size is 1xN or Nx1.
   Additionally, if the vector data set has X axes defined, it returns X, for 
   instance with event data sets.

 input:  s: object or array (iData)
 output: b: object or array (iData)
 ex:     b=isvector(a);
