Error in HSTWCS docs example

[s-goldman]

In the HSTWCS docs example a line suggests that using

w = wcsutil.HSTWCS(instrument='DEFAULT')

should work but instead returns an error:

TypeError: HSTWCS.__init__() got an unexpected keyword argument 'instrument'

To clarify, the DEAFAULT option aws an unsuccessful attempt to make drizzlepac work with data from any telescope. At the end it's HST specific.

@nden Okay great, thanks for the context. In that case, can I remove it from the docs?
