A data analysis library comparable to pandas

# Installation

You must have cython installed. Run `python setup.py build_ext --use-cython -i`

# Main Goals

* A minimal set of features 

* Be as explicit as possible

* There should be one-- and preferably only one --obvious way to do it.

### Data Structures

* Only DataFrames

* No Series

### Only Scalar Data Types

All data types allow nulls

- [x] bool - always 8 bits

- [x] int

- [x] float

- [x] str - stored as a categorical

- [x] datetime

- [x] timedelta

### Column Labels

* No hierarchical index

* Column names must be strings

* Column names must be unique

### Row Labels

* No row labels for now

* Only a number display on the output

### Subset Selection

* Only one way to select data - `[ ]`

* Subset selection will be explicit and necessitate both rows and columns

* Rows will be selected only by integer location

* Columns will be selected by either label or integer location. Since columns must be strings, this will not be amibguous

* Slice notation is also OK

### Development

* Must use type hints

* Must use 3.6+ - fstrings

* numpy

### Advantages over pandas

* Easier to write idiomatically

* String processing will be much faster

* Nulls allowed in each data type

* Nearly all operations will be faster
