added __init__.py to root
undid my too-clever metadatum for more common metadata
removed manual keywords in VWClient.search in favor of **kwargs and user resp to use VW standard key/val pairs. Removed fetch_records
updated the metadata makers to add in times, but this will be removed for now in a separate branch so the useful fixes can be integrated
removed startTime and endTime from JSON metadata from the script_fixes branch, keeping all other modifications
all tests passing with model_vars and a cleaned-up implementation of building the JSON metadata. Now insert doesn't also glue together XML into JSON. Now must pass XML to makeWatershedMetadata
added full example of metadata building and watershed upload/insert and quickstart guide
