Made some refactoring, fixed some potential issues

[edwardt]

Hi,

Made some refactoring summary:

• Break up client.cs into individual logical entities
• promote some common code/behavior in responses to base class
• made abstract class on client to interface since no behavior inheritance
• put check keys before adding to dictionary or else exception will occur
• grouping files into separate folders in solutions
• close response stream on GetObject
• rename some classes name to reflect intentions.
• add a custom constructor on client to allow configurable timeout and chucksize

The first 12 checkins had poor comments .. at that point I didn't intend for a merge up but just checking out the code.
not sure how to edit those comment outs .......... but the code changes are not that junk

[edwardt]

use stash to clean up the "in-between" comments.
put a branch instead of master for this pull request
may be add more info on readme for this dll

Looks good to me. Was that last comment for me to do or have you already done it?

Thanks!

No more changes. I should have given u a branch instead of the master .. and squash the extra comments.
please do the up merge. Anywork I am going forward will be on a seperate branch.
BTW, have you tested this api against auth.api.rackspacecloud.com/v1.0/ ??????
