Refactored out most of internal work for summarizing data opening
the door for generating charts from it. A model is introduced
to hold information needed for a summary, Histogram command is
an example of a partial usage. This is the beginning.
Removed implicit arithmetic traits on Value and Primitive to avoid
mixed types panics. The std operations traits can't fail and we
can't guarantee that. We can handle gracefully now since compute_values
was introduced after the parser changes four months ago. The handling
logic should be taken care of either explicitly or in compute_values.
The zero identity trait was also removed (and implementing this forced
us to also implement Add, Mult, etc)
Also: the `math` operations now remove in the output if a given column is not computable:
```
> ls | math sum

```
* Delete unnecessary match
* Use `unwrap_or_else()`
* Whitespace was trim on file save
* Use `map_or_else()`
* Use a default to group all match arms with same output
* Clippy made me do it
* added helper to convert data to strings
added ability to auto-rotate single row output
if row will be greater than terminal width
* Added pivot_to_fit config value
* Added ColumnPath to convert_to_string helper
* Figured out I had to run `cargo fmt --all -- --check`

* figuring out error with lines
* make progress in printing of block
* support for external commands; fix some tiny bugs in formatting
* basic printing of block; going to experiment with bubbling raw input to the command itself to avoid potential edge cases
* remove fmt::Display impls for hir structs; bubbled raw_input to command args
* compiling checkpoint :)
* process raw input alias to remove save flag; do duplicates stored
* fix warnings; run clippy
* removed tmux log file
* fix bug in looking for same alias; changed unwraps to safe unwraps
* Refactor InputStream and affected commands.
First, making `values` private and leaning on the `Stream` implementation makes
consumes of `InputStream` less likely to have to change in the future, if we
change what an `InputStream` is internally.
Second, we're dropping `Option<InputStream>` as the input to pipelines,
internals, and externals. Instead, `InputStream.is_empty` can be used to check
for "emptiness". Empty streams are typically only ever used as the first input
to a pipeline.
* Add run_external internal command.
We want to push external commands closer to internal commands, eventually
eliminating the concept of "external" completely. This means we can consolidate
a couple of things:
- Variable evaluation (for example, `$it`, `$nu`, alias vars)
- Behaviour of whole stream vs per-item external execution
It should also make it easier for us to start introducing argument signatures
for external commands,
* Update run_external.rs
* Update run_external.rs
* Update run_external.rs
* Update run_external.rs

* Making Commands match what UntaggedValue needs
* WIP
* WIP
* WIP
* Moved to expressions for conditions
* Add 'each' command to use command blocks
* More cleanup
* Add test for 'each'
* Instead use an expression block
