fbc6f01cfb Add =~ and !~ operators on strings
`left =~ right` return true if left contains right, using Rust's
`String::contains`. `!~` is the negated version.

A new `apply_operator` function is added which decouples evaluation from
`Value::compare`. This returns a `Value` and opens the door to
implementing `+` for example, though it wouldn't be useful immediately.

The `operator!` macro had to be changed slightly as it would choke on
`~` in arguments.

5fbea31d15 Remove unused Display implementations
After the previous commit, nushell uses PrettyDebug and
PrettyDebugWithSource for our pretty-printed display output.

PrettyDebug produces a structured `pretty.rs` document rather than
writing directly into a fmt::Formatter, and types that implement
`PrettyDebug` have a convenience `display` method that produces a string
(to be used in situations where `Display` is needed for compatibility
with other traits, or where simple rendering is appropriate).

b3c021899c combine functions behind to/from-c/tsv commands
fixes #969, admittedly without a --delimiter alias

moves from_structured_data.rs to from_delimited_data.rs to better
identify its scope and adds to_delimited_data.rs. Now csv and tsv both
use the same code, tsv passes in a fixed '\t' argument where csv passes
in the value of --separator

a3ff5f1246 Updates tests for from tsv, csv, and ssv.
With the proposed changes, these tests now become invalid. If the first line is
to be counted as data, then converting the headers to ints will fail. Removing
the headers and instead treating the first line as data, however, reflects the
new, desired mode of operation.

00b3c2036a This is part of on-going work with capabilities when working with
tables and able to work with them for data processing & viewing
purposes. At the moment, certain ways to process said tables we
are able to view a histogram of a given column.

As usage matures, we may find certain core commands that could
be used ergonomically when working with tables on Nu.

passes it to csv::ReaderBuilder via .delimiter() method as a u8.

392ff286b2 This commit is ongoing work for making Nu working with data processing
a joy. Fundamentally we embrace functional programming principles for
transforming the dataset from any format picked up by Nu. This table
processing "primitive" commands will build up and make pipelines
composable with data processing capabilities allowing us the valuate,
reduce, and map, the tables as far as even composing this declartively.

On this regard, `split-by` expects some table with grouped data and we
can use it further in interesting ways (Eg. collecting labels for
visualizing the data in charts and/or suit it for a particular chart
of our interest).

6a7c00eaef Finish the job of moving shapes into the stream
This commit should finish the `coloring_in_tokens` feature, which moves
the shape accumulator into the token stream. This allows rollbacks of
the token stream to also roll back any shapes that were added.

This commit also adds a much nicer syntax highlighter trace, which shows
all of the paths the highlighter took to arrive at a particular coloring
output. This change is fairly substantial, but really improves the
understandability of the flow. I intend to update the normal parser with
a similar tracing view.

In general, this change also fleshes out the concept of "atomic" token
stream operations.

A good next step would be to try to make the parser more
error-correcting, using the coloring infrastructure. A follow-up step
would involve merging the parser and highlighter shapes themselves.
