Use lists.

While trying to create a series of labeled points, I noticed some 
inconsistent behavior in pylab.
It is not possible to plot a single point. For example:
plot (0.4,0.6,'+'); #fails
It is possible to work around this with:
text(0.4, 0.6,'+', 
horizontalalignment='center',verticalalignment='center')
but that seems to be counter to the philosophy that simple plots 
should be simple to make, and plotting commands should just work.
In a similar vein, it seems vectors could be added to text by 
allowing a user to plot a list of strings at an array of points.
These two additions would make is so one could either loop over a 
series of points, adding labels for each loop, or plot all the points 
and all the labels with two simple commands. Both seem like 
reasonable things to do, and both should be supported.
