update resource.conf file comment on cors-hosts
File loader now uses relative paths from the loading root for storage dataSets (not absolute paths from the filesystem root)
. loading a file with no dataset (e.g. because the filename begins with an underscore) now goes into the "default" dataset

add ExecutionContext to custom selectors

by popular demand, move log file into /tmp by default

Test improvements:
. make sure there are no dots in test keyspace names
. move integration test resources to 'it' configuration,
. Added close() on FileLoader and WatchPath for test cleanup
. refactor TestDataService fixture to allow for easier reuse from external tests
new standard transforms:
  summarizeSum, summarizeMean, summarizeRandom

improve logging of requests/responses
. log json requests/responses
. full detail of http headers at trace level
. add clientIP to request logging
. create logging directive

start on repl plot tool
. plot navigates to plot dashboard

reorganize spray route handling

set default main class for launching the server (in sbt run and reStart)

fix bug in command line parameters for web-root

update sample dashboard to current form of file-loader produced columns

fix issue: minimum step size should be one for summary transforms
fix DomainRange format: it had an extra set of brackets
. forward looking support for more transforms with StandardObjectTransform..
. Drop inner transform-only unit test, the protocol test should be enough coverage

Fix some edge cases in summarizing

Return more protocol errors as Status messages instead of http errors
. catch internal exceptions with handleExcpetions handler
. 999 error code is a catchall, these should all be replaced with specific error messages

Partial support for new style range selectors: start,until,limit
. Add SelectRanges, to factor out fetching 'RangeInterval' based ranges for transforms
. Add explicit types for SummaryParameters, and RawParameters. They both
  include range selectors, but they're not the same.

Tests
. Factor out some more common code in testing summaries
. partial coverage for new style range selectors

Add summarizeCount (partial implementation: works for numeric values but not string values)

simplify Column interface, using half-bounded ranges + limit covers all current use cases

add test to verify summarization when requested maxResults is larger than the number of events in the partition

interim work towards console plotting
. store plot parameters and pass session to js

js
. minor refactoring of data request api to support more transform types
. better support for chart padding in Y
. support non-time based xAxes
. simple scatter plot, makes me smile
fix some error logging

support for JsValues in cassandra and columns

more interim work on plotting
. trigger plot drawing based on the plotParameters
. pass units label to the plot
