Changed the first two sentences about AWIPS and Unidata so they do not start with an acronym, and properly place the acronym in parenthesis after the definition.
Fix a broken link for the IDD in the second paragraph.
Updated the Cloud section to use "... an EDEX..." instead of "...a EDEX...". Also, updated the text to say the cloud edex is available to the community, more vaguely, because it is not just limited to the "Unidata university community".
Updated the Distributed Computing section to be a little more legible. Previously the text was a bit confusing and had a bit of a run on sentence -- broke those up to be easier to read. Also changed the last sentence to be more present tense since GOES-16 data is now available (not a future event anymore).
Changed the PyPIES header so that the link from the Software Components section now works.
Added some periods at the end of sections so that they were all consistent.
