Remove masked elements from an array

[PoulsenL at capecon.com]

I have a Numeric array with missing elements from which I wish to calculate
a histogram.  However, in order to do so I must first remove the 'None'
values from the array.  I have a kludgy solution, but I was wondering if
someone could point me in the right direction on what is the proper method
of collapsing a masked array to just the non-masked values.

Thanks
