DOC: Clarify behavior in np.random.uniform 
Although the arguments are specified as 'high'
and 'low', it is possible to pass in values for
'low' and 'high' where 'low' >= 'high' and still
obtain well-defined behavior. The documentation
has been expanded to reflect this fact, with a
note to discourage passing in arguments satisfying
'low' > 'high'.

anywhere within the interval ``[a, b)``, and zero elsewhere.

When ``high`` == ``low``, values of ``low`` will be returned.
If ``high`` < ``low``, the results are officially undefined
and may eventually raise an error, i.e. do not rely on this
function to behave when passed arguments satisfying that
inequality condition.
