• Table variant of the Text.split and Text.tokenize.
• Split to rows or to new columns.
• In-Memory for v1, should report unsupported on the database.

## Splits a column of text into a set of new columns.
   The original column will be removed from the table.
   The new columns will be named with the name of the input with a incrementing number after.

   Arguments:
   - column: The column to split the text of.
   - delimiter: The term or terms used to split the text.
   - column_count: The number of columns to split to. 
     If `Auto` then columns will be added to fit all data.
     If the data exceeds the number of columns, a `Column_Count_Exceeded` error 
     will follow the `on_problems` behavior.
   - on_problems: Specifies the behavior when a problem occurs.
Table.split_to_columns : Text | Integer -> Text -> Auto | Integer -> Problem_Behavior -> Table
Table.split_to_columns self column delimiter="," column_count=Auto on_problems=Report_Error = ...

## Splits a column of text into a set of new rows.
   The values of other columns are repeated for the new rows.

   Arguments:
   - column: The column to split the text of.
   - delimiter: The term or terms used to split the text.
   - on_problems: Specifies the behavior when a problem occurs.
Table.split_to_rows : Text | Integer -> Text -> Problem_Behavior -> Table
Table.split_to_rows self column delimiter="," on_problems=Report_Error = ...

## Splits a column of text into a set of new columns using a regular expression.
   If the pattern contains marked groups, the values are concatenated together 
   otherwise the whole match is returned.
   The original column will be removed from the table.
   The new columns will be named with the name of the input with a incrementing number after.

   Arguments:
   - column: The column to tokenize the text of.
   - pattern: The pattern used to find within the text.
   - case_sensitivity: Specifies if the text values should be compared case
     sensitively.
   - column_count: The number of columns to split to. 
     If `Auto` then columns will be added to fit all data.
     If the data exceeds the number of columns, a `Column_Count_Exceeded` error 
     will follow the `on_problems` behavior.
   - on_problems: Specifies the behavior when a problem occurs.
Table.tokenize_to_columns : Text | Integer -> Text -> Case_Sensitivity -> Auto | Integer -> Problem_Behavior -> Table
Table.tokenize_to_columns self column pattern="." case_sensitivity=Case_Sensitivity.Sensitive column_count=Auto on_problems=Report_Error =

## Takes a regular expression pattern and returns all the matches as new rows.
   If the pattern contains marked groups, the values are concatenated together 
   otherwise the whole match is returned.
   The values of other columns are repeated for the new rows.

   Arguments:
   - column: The column to split the text of.
   - pattern: The pattern used to find within the text.
   - case_sensitivity: Specifies if the text values should be compared case
     sensitively.
   - on_problems: Specifies the behavior when a problem occurs.
