This PR moves the `Table` class out of the Vector hierarchy and adds optimized dataframe operations to it. Currently implements an optimized `scan()` method, `filter(predicate)`, `count()`, and `countBy(column_name)` (only works on dictionary-encoded columns).
Some usage examples, based on the file generated by `js/test/data/tables/generate.py`:
``` js
> let table = Table.from(...);
> table.count()
1000000
> table.filter(col('lat').gteq(0)).count()
499718
> table.countBy('origin').toJSON()
{ Charlottesville: 166839,
'New York': 166251,
'San Francisco': 166642,
Seattle: 166659,
'Terre Haute': 166756,
'Washington, DC': 166853 }
> table.filter(col('lng').gteq(0)).countBy('origin').toJSON()
{ Charlottesville: 83109,
'New York': 83221,
'San Francisco': 83515,
Seattle: 83362,
'Terre Haute': 83314,
'Washington, DC': 83479 }
```
There are performance tests for the dataframe operations, to run them you must first generate the test data by running `npm run create:perfdata`.
The PR also includes @trxcllnt's refactor of the JS implementation to make it more closely resemble the C++ implementation. This refactor resolves multiple JIRAs: ARROW-1903, ARROW-1898, ARROW-1502, ARROW-1952 (partially), and ARROW-1985

I am contributing to [Arrow 3731](https://issues.apache.org/jira/browse/ARROW-3731). This PR has the minimum functionality to read parquet files into an arrow::Table, which can then be converted to a tibble. Multiple parquet files can be read inside `lapply`, and then concatenated at the end. Steps to compile 1) Build arrow and parquet c++ projects 2) In R run `devtools::load_all()` What I could use help with: The biggest challenge for me is my lack of experience with pkg-config. The R library has a `configure` file which uses pkg-config to figure out what c++ libraries to link to. Currently, `configure` looks up the Arrow project and links to -larrow only. We need it to also link to -lparquet. I do not know how to modify pkg-config's metadata to let it know to link to both -larrow and -lparquet Author: Jeffrey Wong <[email protected]> Author: Romain Francois <[email protected]> Author: jeffwong-nflx <[email protected]> Closes apache#3230 from jeffwong-nflx/master and squashes the following commits: c67fa3d <jeffwong-nflx> Merge pull request #3 from jeffwong-nflx/cleanup 1df3026 <Jeffrey Wong> don't hard code -larrow and -lparquet 8ccaa51 <Jeffrey Wong> cleanup 75ba5c9 <Jeffrey Wong> add contributor 56adad2 <jeffwong-nflx> Merge pull request #2 from romainfrancois/3731/parquet-2 7d6e64d <Romain Francois> read_parquet() only reading one parquet file, and gains a `as_tibble` argument e936b44 <Romain Francois> need parquet on travis too ff260c5 <Romain Francois> header was too commented, renamed to parquet.cpp 9e1897f <Romain Francois> styling etc ... 456c5d2 <Jeffrey Wong> read parquet files 22d89dd <Jeffrey Wong> hardcode -larrow and -lparquet

https://issues.apache.org/jira/browse/ARROW-3923 Hello! I was reading through the JDBC source code and I noticed that a java.util.Calendar was required for creating an Arrow Schema and Arrow Vectors from a JDBC ResultSet, when none is required. This change makes the Calendar optional. Unit Tests: The existing SureFire plugin configuration uses a UTC calendar for the database, which is the default Calendar in the existing code. Likewise, no changes to the unit tests are required to provide adequate coverage for the change.

This updates the language in `install_arrow()` to follow the README revision that will land in https://github.com/apache/arrow/pull/4948/files#diff-563b2cb2c8c2d51b2ff6b177e2d84286R33. The [Jira ticket](https://issues.apache.org/jira/browse/ARROW-6142) requested three things; this is `#2` in the list. On `#1`, I defer to the C++ installation docs, which are already included in the install_arrow message, rather than duplicating content here. `#3` is out of scope. Closes apache#5027 from nealrichardson/no-ppa and squashes the following commits: 80b142e <Neal Richardson> s/arrow/Arrow/ 44c9659 <Neal Richardson> Tweak language again 36cfe28 <Neal Richardson> Further linux install revisions 79bd7e0 <Neal Richardson> One more PPurge 63f75bd <Neal Richardson> Revise install_arrow instructions for Linux Authored-by: Neal Richardson <[email protected]> Signed-off-by: Sutou Kouhei <[email protected]>
